[time relay]SSJ-21A type static time relay

2026-6-10 12:25:44

1�� Overview

1. Main purpose of the product
The SSJ series static time relay (hereinafter referred to as the relay) is used in the secondary circuit relay protection and automatic control circuit of the power system as a delay device to enable the controlled components to obtain the required delay. This relay is an integrated circuit static relay with high precision, low power consumption, accurate action time, intuitive and convenient setting, and wide range. The working power supply adopts switch power conversion and is universal for AC and DC, completely replacing electromagnetic time relays.

2�� Classification and Meaning of SSJ-21A Static Time Relay Models

Comparison table between this relay model and the replaced old model:

3�� Product composition and working principle

1. This relay has a much higher delay accuracy than the DS type electromagnetic time relay, which can meet the requirements of shortening the protection time difference in power system relay protection. It is currently an ideal replacement product for time relays. The external structure, internal wiring, working mode, and setting range of this relay are the same as those of the DS series time relay, except for the setting mode. The setting time is calculated by multiplying the three digits of the dip switch by the 0.01s or 0.1s time base. Changing the setting value does not require verification.
2. This relay is an action delay digital time relay composed of imported CMOS integrated circuits. The relay consists of an oscillator, a frequency divider, and a three-stage pulse counter, and the delay value is set through a BCD code dip switch.
3. Relays are usually not charged. After the rated voltage is applied, the internal instantaneous relay of the relay acts and the crystal oscillator starts oscillating, generating clock pulses that are divided by frequency
Afterwards, the counter counts the number of pulses. When the counted number of pulses reaches the delay setting value, the trigger flips and drives the output relay to operate, achieving the required delay. Due to the use of a crystal oscillator and the addition of a time compensation preset circuit, it strictly conforms to the setting value for extremely short delay values and has extremely high accuracy.
4. The double delay loop of the relay has relatively independent delay and drives one executing relay separately. Therefore, the dynamic closing contacts of the two executing relays can be used as the stopping and sliding contacts of the relay according to the length of the delay. However, after the sliding contact is closed, its closed state remains until the relay loses power and returns. If the user needs the sliding contact to close for a certain period of time and return immediately, they need to specify it when ordering and provide the duration of the sliding contact's closure.
5. The schematic diagram of the relay is shown in Figure 1.

4�� Technical requirements

1. The rated values and specifications are shown in the table above.
2. Delay accuracy
a�� The average error of the delay setting value: Under reference conditions, the absolute value of the average error of the relay delay setting value is not greater than 0.1%+3ms of the setting value; the average error=(average of 5 measurements - setting value)/setting value × 100%.
b�� Delay consistency: Under benchmark conditions, the delay consistency of the relay is not greater than the set value (3-10ms).
c�� At temperatures ranging from -10 to 50 ��, the absolute value of the average error (including consistency) of any delay setting value shall not exceed 0.1%+5ms of the setting value
3. Working voltage: When the operating voltage is not greater than 70% of the rated voltage, the relay should work reliably.
4. Return time of relay
The time for the outlet contact to return to the starting position after cutting off the electrical power supply should not exceed 25ms for varieties that use DC power supply
5. When the return voltage of the relay decreases by no less than 10% of the rated voltage, the relay contacts should reliably return.
6. Power consumption
DC48V�� Not exceeding 2W
DC110V or AC100-127V, not exceeding 4.5W (6.5VA)
DC or AC220V, not exceeding 8.1W (13VA).
7. Thermal performance requirements
This series of relays can operate for a long time when powered on, and can withstand 1.1 times the rated voltage value for a long time when the ambient temperature is 50 ��.
8. Power supply working characteristics: The power supply can slowly rise and fall, suddenly turn on/off, or supply power through shaking contacts. The relay can work normally and there is no zero second outlet or instantaneous outlet phenomenon.

The customer needs to return immediately after the sliding contact is closed for a certain period of time. When placing an order, it is necessary to specify and provide the duration of the sliding contact's closure.

[time relay]JSH-10 series high-precision time relay

2026-6-10 12:20:54

1. Overview:

The JHS series static AC power-off delay relay is used in relay protection and automation circuits for AC operation, as a time element for delayed return after AC instantaneous action power-off. The relay can replace the DSJ-10 series electromagnetic time relay, and the wiring form of the two is completely the same, so there is no need to change any wiring. This product overcomes the quality problems of DSJ10, such as large delay error, high noise, and delayed movement of moving contacts; This product has the characteristics of high delay accuracy, sensitive and reliable operation, and can be selected from any of the three structures.

2. Structure and working principle:
The JHS-1 relay adopts a protruding fixed structure for the housing structure, and the external shape and installation hole size are detailed in the attached figure.
The JHS-2 relay adopts a protruding plug-in structure for the housing structure, and the external shape and installation hole size are detailed in the attached figure.
The JHS-3 relay adopts a Xuji embedded plug-in structure for its housing structure. The appearance and installation hole size are detailed in the attached figure.
Relays consist of crystal oscillators, frequency dividers, setting switches, drive circuits, and power circuits. When the rated point voltage is applied to the relay, the internal instantaneous relay and two delay relays of the relay act instantaneously, the contacts switch, and the power circuit and timing circuit are in a power-off state to improve the anti-interference performance of the relay. When the input voltage drops significantly or completely disappears, the instantaneous relay returns instantly (the two delay execution relays are still in action), and the contacts also return instantly, connecting the energy storage power supply to the timing circuit. The crystal oscillates to generate a clock pulse, which is divided into 10ms. The counter counts the timing pulse, and when the counted pulse number matches the set switch value, it drives the execution relay to return, completing the function of delayed return after power failure.
3. Instructions for use

The delay return time t1 of relay K1 is set by the upper three digit switch, and the delay return time t2 of relay K2 is set by the lower three digit switch. The time setting value is obtained by multiplying the three digit switch by 0.01S. For example, if the three digit setting is 580, the time setting value is 580 × 0.01S=5.8S. The setting values of t1 and t2 can be equal or not equal.
4. Main technical parameters
4.1 Rated voltage: AC 380220, 110, 100V.
4.2 Rated frequency: 50HZ or 60HZ.
4.3 Ensure that the voltage required for reliable energizing of relay contacts is not greater than 80% of the rated voltage.
4.4 Ensure that the reliable power-off return voltage of the relay is not less than 10% of the rated voltage.
4.5 The delay error of relay power-off delay return under rated voltage shall not exceed 0.1% of the setting value ÷ 10ms within the setting range
4.6 The variation of relay power-off delay under rated voltage shall not exceed 0.1% of the rated value ÷ 10ms. Variation refers to the difference between the maximum and minimum values of the relay measured five times at the same time setting point.
The contact points for the delayed return of the 4.7 second set can be independently set, with a time setting range of 0.02-99.99 seconds, and the delay setting values can be different or the same.
4.8 The power consumed by the relay at rated voltage shall not exceed 4VA.
4.9 Relays are allowed to withstand 110% of rated voltage for a long time.
4.10 Relays with a voltage not exceeding 250V, current not exceeding 1A (time constant T=5 ± 0.75ms in DC circuits), and a contact breaking capacity of 30W. In AC circuits with a voltage not exceeding 250V, current not exceeding 1A, and power factor COS0:0.4+0.1, the contact
The disconnect capacity is 150VA.
4.1l The effective voltage between each circuit of the relay and the exposed non charged metal parts should be able to withstand 2kV, and the input circuit and contacts should be able to withstand 1kV, 50HZ AC voltage. After a 1-minute experiment, there should be no insulation breakdown or flashover phenomenon.
4.12 The relay can operate reliably within the temperature range of -10 ° C to 40 ° C.
4.13 Relay has a mechanical lifespan of 105 times and an electrical lifespan of 104 times.

[time relay]JHS-10 series high-precision time relay

2026-6-10 12:12:27

1�� Overview:

The JHS series static AC power-off delay relay is used in relay protection and automation circuits for AC operation, as a time element for delayed return after AC instantaneous action power-off. The relay can replace the DSJ-10 series electromagnetic time relay, and the wiring form of the two is completely the same, so there is no need to change any wiring. This product overcomes the quality problems of DSJ10, such as large delay error, high noise, and delayed movement of moving contacts; This product has the characteristics of high delay accuracy, sensitive and reliable operation, and can be selected from any of the three structures.

2�� Structure and working principle

The JHS-1 relay adopts a protruding fixed structure for the housing structure, and the external shape and installation hole size are detailed in the attached figure.
The JHS-2 relay adopts a protruding plug-in structure for the housing structure, and the external shape and installation hole size are detailed in the attached figure.
The JHS-3 relay adopts a Xuji embedded plug-in structure for its housing structure. The appearance and installation hole size are detailed in the attached figure.
Relays consist of crystal oscillators, frequency dividers, setting switches, drive circuits, and power circuits. When the rated point voltage is applied to the relay, the internal instantaneous relay and two delay relays of the relay act instantaneously, the contacts switch, and the power circuit and timing circuit are in a power-off state to improve the anti-interference performance of the relay. When the input voltage drops significantly or completely disappears, the instantaneous relay returns instantly (the two delay execution relays are still in action), and the contacts also return instantly, connecting the energy storage power supply to the timing circuit. The crystal oscillates to generate a clock pulse, which is divided into 10ms. The counter counts the timing pulse, and when the counted pulse number matches the set switch value, it drives the execution relay to return, completing the function of delayed return after power failure.
3�� Usage:
The delay return time t1 of relay K1 is set by the upper three digit switch, and the delay return time t2 of relay K2 is set by the lower three digit switch. The time setting value is obtained by multiplying the three digit switch by 0.01S. For example, if the three digit setting is 580, the time setting value is 580 × 0.01S=5.8S. The setting values of t1 and t2 can be equal or not equal.
4�� Main technical parameters

2026-6-10 12:08:16

1 Purpose

The DS-20 series time relay is used as an auxiliary component in various protection and automatic circuits, enabling adjustable delay in the operation of the controlled components.
Working principle and structure of DS-20 series time relay
2.1 The relay is a delayed suction electromagnetic relay. The relay has one instantaneous conversion contact, one sliding delay closing main contact, and one termination delay closing main contact.
When voltage is applied to both ends of the relay coil, the armature (iron core) is sucked in, the instantaneous dynamic contact is closed, the instantaneous dynamic contact is opened, and the delay mechanism starts to start at the same time. Under the action of the tension spring in the delay mechanism, after a set time, the sliding contact closes. After a certain amount of time, the endpoint contact will close. The period from the moment the voltage is applied to the coil to the time when the delayed closing contact is closed can be adjusted by moving the position of the static contact, and indicated directly on the scale of the relay by the pointer. When the coil is powered off, the chirp and delay mechanism instantly return to their original positions under the force of the tower shaped reaction spring.
2.3 Relays have two structures:
2.3.1 Protruding plug-in structure. The Aji JK-1 type housing is used, and its external drawing and opening diagram are shown in Appendix I. The internal wiring of the relay is shown in Figure 1.
2.3.2 Embedded plug-in structure (with/Q in the model). The Xuji A11K shell is used, and its external drawing and opening diagram are shown in Appendix II. The internal wiring of the relay is shown in Figure 2.
If the wiring method behind the board needs to be changed to the wiring method in front of the board, a wiring socket and a middle frame in front of the board should be added, as shown in Appendix II.

[time relay]DS-110/120 series time relay

2026-6-10 12:07:42

1 DS-110/120 series time relay application

This series of time relays is used in various protection and automatic circuits to provide adjustable delay for the action of controlled components.
Overview of Structure 2
The relay is a suction type electromagnetic relay with a delay mechanism.
The relay has one instantaneous conversion contact and one delayed closing main contact. For DS-1141115116124125126 relay, there is an additional delayed sliding main contact.
The coil of the relay is fixed inside the U-shaped magnet. When a voltage is applied to both ends of the coil, the armature (iron core) is sucked in, and the instantaneous dynamic contact is closed and the dynamic contact is disconnected. At the same time, the delay mechanism starts to move. Under the action of the tension spring of the delay mechanism, after a certain period of time (setting time), the main contact of the delayed dynamic contact is closed (for DS-114, 115, 116, 124, 125, 126 relays, the sliding main contact is closed first, and then the main contact of the delayed dynamic contact is closed after a certain period of time). The time (i.e. delay) from the moment of applying voltage to the moment of closing the main contact of the relay can be adjusted by changing the position of the static contact, and indicated directly on the scale plate of the relay by the pointer. When the coil breaks the circuit, the relay and delay mechanism return to their original positions instantaneously under the action of the tower spring.

[time relay]ZSJ series DC power-off delay relay

2026-6-10 12:07:34

ZSJ series DC power-off delay relay uses:

The ZSJ series static DC power-off delay relay is used in DC operated relay protection and automation circuits as a time element for instantaneous action after DC power on and delayed return after power-off.

ZSJ series DC power-off delay relay model name:

There are three types of ZSJ series relays according to their structure:
The ZSJ-1 relay adopts an upward protruding fixed structure for the housing structure, and its external dimensions and installation hole dimensions are shown in Figure 1 of the general structural system;
The ZSJ-2 relay adopts a protruding plug-in structure for the housing structure, and its external dimensions and installation hole dimensions are shown in Figure 3 of the general structural system;
The ZSJ-3 relay adopts a Xuji embedded plug-in structure for its housing structure, and its external dimensions and installation hole dimensions are shown in Figure 7 of the general structural system.

Working Principle:
The principle block diagram of the relay is shown in Figure 1. As shown in the figure, the relay consists of a crystal oscillator, a frequency divider, a counter, a setting switch, a driving circuit, and a power supply circuit. When the rated voltage is applied to the relay, the internal instantaneous relay and two delay execution relays perform instantaneous actions, switch contacts, and disconnect the power circuit from the timing circuit. Therefore, the timing circuit is in a power-off state to improve the anti-interference performance of the relay. When the input voltage significantly decreases or completely disappears, the instantaneous relay returns instantly. (Two delay execution relays are still in action), and the contacts also instantly return, connecting the energy storage power supply to the timing circuit. The crystal oscillates to generate clock pulses, which are divided into 10ms. The counter counts the timing pulses, and when the counted number of pulses matches the preset value of the setting switch, it drives the execution relay to return, completing the function of power-off delay return.

Usage:
The relay panel diagram is shown in Figure 2. The upper three digit switch in the diagram sets the delay return time t1 of relay K1, and the lower three digit switch sets the delay return time t2 of relay K2. Multiplying the three digit switch by 0.01S is the time setting value. For example, if the three digit setting is 580, the time setting value is 580 × 0.01S=5.8S. The setting values of t1 and t2 can be equal or not equal.

Main technical parameters:
6.1 Rated voltage: DC 220V, 110V, 48V, 24V.
6.2 Ensure that the voltage required for reliable energizing of relay contacts is not greater than 70% of the rated voltage.
6.3 Ensure that the reliable power-off return voltage of the relay is not less than 10% of the rated voltage.
6.4 The delay error of relay power-off delay return under rated voltage shall not exceed 0.1% of the setting value+10ms within the setting range
6.5 The variation of relay power-off delay under rated voltage shall not exceed 0.1% of the rated value+10ms. Variation refers to the difference between the maximum and minimum values of the relay measured five times at the same time setting point.
6.6 The two delayed return contacts can be independently set, with a time setting range of 0.02-9.99s, and the delay setting values can be different or the same.
6.7 The power consumed by the relay at rated voltage shall not exceed 4W.
6.8 Relays are allowed to withstand 110% of rated voltage for a long time.
The contact breaking capacity of the 6.9 relay in a DC inductive circuit with a time constant T=5 ± 0.75ms and a voltage not exceeding 250V and a current not exceeding 1A is 30W.
6.10 The effective voltage between each circuit of the relay and the exposed non charged metal parts should be able to withstand 2KV, and the input circuit and contacts should be able to withstand 1kV, 50HZ AC voltage. After a 1-minute experiment, there should be no insulation breakdown or flashover phenomenon.
6.11 The relay can reliably operate within the temperature range of -10 �� to 40 ��.
6.12 Relay has a mechanical lifespan of 10 ^ 5 times and an electrical lifespan of 10 ^ 4 times.
6.13 Relay weight: approximately 0.5kg.

Wiring diagram behind the relay:
The wiring terminal diagram of the relay is shown in Figure 3. The contacts in the diagram are the state after the relay loses power. When the rated DC voltage is applied, the instantaneous contact K3, the contact K1 with a delay time of t1, and the contact K2 with a delay time of t2 all act simultaneously. At this time, the contact state is opposite to that shown in Figure 3. When the applied voltage suddenly loses power (voltage), the instantaneous contact K3 immediately returns, and the delayed contact K1 returns after a delay of t1 after power failure. Similarly, the delayed contact K2 returns after a delay of t2 after power failure. The contact state after return is shown in Figure 3.

2026-6-10 12:06:33

Application of ZSJ-4 DC power-off delay relay:

The ZSJ series static DC power-off delay relay is used in DC operated relay protection and automation circuits as a time element for instantaneous action after DC power on and delayed return after power-off.

Working Principle:
The principle block diagram of the relay is shown in Figure 1. As shown in the figure, the relay consists of a crystal oscillator, a frequency divider, a counter, a setting switch, a driving circuit, and a power supply circuit. When the rated point voltage is applied to the relay, the internal instantaneous relay and two delay execution relays perform instantaneous actions, switch contacts, and disconnect the power circuit and timing circuit, so that the timing circuit is in a power-off state to improve the anti-interference performance of the relay. When the input voltage significantly decreases or completely disappears, the instantaneous relay returns instantly. (Two delay execution relays are still in action), and the contacts also instantly return, connecting the energy storage power supply to the timing circuit. The crystal oscillates to generate clock pulses, which are divided into 10ms. The counter counts the timing pulses, and when the counted number of pulses matches the preset value of the setting switch, it drives the execution relay to return, completing the function of power-off delay return.

Usage:
The relay panel diagram is shown in Figure 2. The upper three digit switch in the diagram sets the delay return time t1 of relay K1, and the lower three digit switch sets the delay return time t2 of relay K2. Multiplying the three digit switch by 0.01S is the time setting value. For example, if the three digit setting is 580, the time setting value is 580 × 0.01S=5.8S. The setting values of t1 and t2 can be equal or not equal.

5.5 The variation of relay power-off delay under rated voltage shall not exceed 0.1% of the rated value+10ms. Variation refers to the difference between the maximum and minimum values of the relay measured five times at the same time setting point.
5.6 The two delayed return contacts can be independently set, with a time setting range of 0.02s-9.99s, and the delay setting values can be different or the same.
5.7 The power consumed by the relay at rated voltage shall not exceed 4W.
5.8 Relays are allowed to withstand 110% of rated voltage for a long time.
The contact breaking capacity of the 5.9 relay in a DC inductive circuit with a time constant T=5 ms ± 0.75ms and a voltage not exceeding 250V and a current not exceeding 1A is 30W.

After a 1-minute experiment, there should be no insulation breakdown or flashover phenomenon.

5.12 Relay has a mechanical lifespan of 105 times and an electrical lifespan of 104 times.
5.13 Relay weight: approximately 0.5kg.

Wiring diagram behind ZSJ-4 DC power-off delay relay:
The wiring terminal diagram of the relay is shown in Figure 3. The contacts in the diagram are the state after the relay loses power. When the rated DC voltage is applied, the instantaneous contact K3, the contact K1 with a delay time of t1, and the contact K2 with a delay time of t2 all act simultaneously. At this time, the contact state is opposite to that shown in Figure 3. When the applied voltage suddenly loses power (voltage), the instantaneous contact K3 immediately returns, and the delayed contact K1 returns after a delay of t1 after power failure. Similarly, the delayed contact K2 returns after a delay of t2 after power failure. The contact state after return is shown in Figure 3.
