Working principle diagram and explanation

The power isolation sampling element connected in series in the DC signal circuit converts the continuous (rectangular) current pulse added in the circuit into a voltage signal and isolates it from the DC signal circuit. This voltage signal is detected by the action pulse width discrimination element after passing through the sudden change pulse detection element, and then sent to the signal self holding and release element for self holding. After being delayed by the action delay element, it reaches the output element and turns on the warning signal alarm bell. If the current in the signal circuit decreases by one circuit before the action delay element is delayed, the sudden change pulse detection element detects the reduced sudden change pulse, and after returning to the reset pulse width discrimination element, the signal self holding and release element returns. The action delay element returns, and the entire impulse relay returns. This is applied to the case of delay warning signal. The sentence is:. If applied to instantaneous warning signals or accident signals, switches S1 and S2 are opened. At this time, the reset pulse width discrimination element and the action delay element are both released. After adding one circuit to the signal circuit, the impulse relay immediately acts, and even if the pulse disappears, it does not return. After the impulse relay acts, the signal self holds and the release element returns through the delay of the reset delay element, and the impulse relay returns. If automatic reset is not required, S3 can be turned on, and the reset delay element is disabled. Simply add power to the reset terminal to return the impulse relay.

Using special sensors and electronic technology, it can withstand strong electrical and magnetic interference from power plants and substations, without misoperation. The impulse action current can be sensitive up to 0.01A, and the steady-state current can be as high as 3.2A. There is absolutely no problem of other impulse relay sampling resistors burning out. It has technical indicators and performance that cannot be compared to existing technology shock relays.

[Impact relay]JC-7 type impulse relay

Purpose:
JC-7 impact relay is mainly used for various fault centralized alarm and start sound in relay protection and safety automatic device circuits, that is, it is a component that repeatedly operates in the central sound alarm circuit of power stations, substations, and related engineering systems.

Relay model name:

Working Principle:
The JC-7 impact relay consists of a transformer, measurement sampling pulse width detection, trigger memory, automatic reset, delayed action and delayed return, and voltage stabilization circuit. When a certain circuit light sign lights up, current flows through the primary winding of the inverter in the relay, inducing a pulse voltage on the secondary winding of the inverter. This voltage is sent to the action measurement and return measurement circuits respectively. Since the action measurement only has output when the light is on and no output when the light is off, the return measurement does not have output at the same time. Therefore, the action measurement and return measurement will not have output at the same time. Then measure the input pulse width detector to avoid relay misoperation caused by induced voltage in the circuit. The pulse width measurement output is sent to the action delay and return delay circuits, and when it meets the set time, it is output to the outlet relay.
Due to the memory function of the triggering circuit, the pulse is no longer detected after the relay is activated until the light signal is turned off or the external reset causes the relay to return, and then the relay enters the loop state again.
The relay has memory functions for both action and return, with the aim of ensuring interoperability between accident and warning signals in starting the audio system. Additionally, the relay is equipped with an external reset interface.

[Impact relay]ZC-23/23A type impulse relay

2026-6-13 18:32:41

ZC-23/23A impact relay is a type of impact relay composed of components such as capacitors, diodes, filters, and reed relays. Relays can be used as centralized signals in relay protection and automatic control systems operated by DC and three-phase full wave rectification power supplies.

Working Principle:
2.1 Action principle: The internal wiring is shown in Figure 1.
Using a differential inverter connected in series in a DC signal circuit, the continuous (rectangular) current pulse or short (pointed) current pulse in the circuit is converted to activate the sensitive element, and then the sensitive element is used to activate the intermediate element of the outlet. The specific working process is as follows:
2.1.1 Relay action
Short circuit terminals 3 and 8 to the positive power supply, short circuit terminals 11 and 16 to the negative power supply, as shown in Figure 2A. When the signal circuit gives an impulse signal (current), it is differentiated by the converter LB and sent to the coil of the sensitive element GHJ to activate the intermediate relay ZJ at the outlet. Then, the ZJ contact starts the bell or whistle to emit an audio signal. When the sharp pulse on the GHJ coil passes, the GHJ contact returns empty load, and ZJ maintains itself by its contact ZJI.
2.1.2 Return process
Press the button FA (or the dynamic breaking contact of the time relay) and it will automatically disconnect after a certain period of time. ��The ZJ coil loses power, all its contacts return, and the audio signal stops. At this point, although the signal circuit current has not disappeared, it has reached a stable di/dt=0, and there is no voltage on the GHJ coil, so it cannot operate (nor maintain). Therefore, all components of the relay have been reset and are ready for a second operation. When the signal (current) in the signal circuit disappears, a reverse pulse is generated on the coil of the sensitive element GHJ due to the action of the differential inverter. This voltage pulse is bypassed by the diode DI, so GHJ does not operate and the entire relay cannot operate.
2.1.3 If an impact automatic reset circuit is required, two impact relays can be connected in reverse series (refer to Figure 2b for specific usage) to achieve it. However, in the case where the signal circuit must be a linear resistor, impact automatic reset can be achieved.

Main technical parameters:
3.1 Rated voltage (VDC): 220110.
3.2 The minimum impulse action current of ZC-23 type impulse relay shall not exceed 0.16A.
3.3 The minimum impulse action current of ZC-23A type impulse relay shall not exceed 0.015A.
3.4 Maximum stable current: ZC-23 is 3.2A, ZC-23A is 0.8A.
3.5 Export intermediate component ZJ: When the ambient temperature is+20 �� and the coil is in a cold state, it should reliably operate at 80% of the rated voltage and reliably return at not less than 5% of the rated voltage.
3.6 At extreme temperatures (+50 ��, -20 ��), the impulse current of the relay shall not exceed 0.2A.
3.7 Disconnecting capacity: The voltage does not exceed 220V, the current does not exceed 0.2A, and the (ZJ contact of the outlet intermediate component) disconnecting capacity is 40W in a DC inductive load (T=5 × 10-3s) circuit, and 50VA in an AC circuit with voltage not exceeding 220V and current not exceeding 0.3A.
3.8 Power consumption
3.8.1 When the primary winding of the converter LB passes a current of 3.2A, its power consumption shall not exceed 7W.
3.8.2 The power consumption of the export intermediate component ZJ shall not exceed 10W at rated voltage.

Relay external dimensions and opening dimensions:
ZC-23 and 23A impact relays have a protruding plug-in structure.
The appearance and installation dimensions of ZC-23 and 23A impact relays are shown in Figure 4 of the universal structural system.

[Impact relay]JC-13,14 type impulse relay

2026-6-13 18:31:21

Purpose:
JC-13�� The 14 type impact relay (hereinafter referred to as the relay) is mainly used for alarm starting sound in various faults of relay protection and safety automatic device circuits. It is a repetitive action component of the central sound alarm circuit in power stations, substations, and related projects.

Relay model name:

Working Principle:
JC-13�� The 14 type relay consists of a transformer, measurement sampling pulse width detection, trigger memory, automatic reset, delayed action and delayed return, and voltage stabilization circuit. The logic diagram is shown in Figure 1.
When a certain circuit light sign lights up, current flows through the primary winding of the inverter of the relay, inducing a pulse voltage on the secondary winding of the inverter. This voltage is sent to the action measurement and return measurement circuits respectively. Since the action measurement only judges the output when the light is on, there is no output when the light is off, and the return measurement only judges the output when the light is off and there is no output when the light is on, the action measurement and return measurement will not have outputs at the same time. The measurement output is sent to the pulse width detector to avoid relay misoperation caused by induced voltage in the circuit. After determining the pulse width, it is sent to the trigger memory circuit, and the output of the trigger memory circuit is sent to the action delay and return delay circuits. After meeting the set time, it is output to the outlet relay.
Due to the memory function of the triggering circuit, when the light sign lights up for the first time, the relay will act. If the light sign lights up again, the circuit will no longer detect pulses until one of the light signs goes out. After the predetermined return time, the relay will return or be reset externally. The relay enters the loop state again.
The relay has a delay circuit for both action and return, aiming to ensure the interoperability of accident and warning signals in the starting audio system. At the same time, the relay is also equipped with an external reset interface. This relay can replace any current impact relay and save users the time relay used in the original equipment.

Main technical parameters:
4.1 DC rated voltage: 48V, 110V, 220V ± 20%, DC ripple<7%
4.2 Minimum impulse action current: JC-13 0.1A; JC-14 0.01A.
4.3 Maximum thermal stability current: JC-13 4A; JC-14 0.8A.
4.4 Minimum impulse return current: JC-13 0.1A; JC-14 0.01A
4.5 Rated number of impact circuits: JC-13 �� 40 circuits; JC-14 �� 80 routes.
4.6 Contact Capacity: In a DC circuit with a voltage not exceeding 250V, a current not exceeding 1A, and a time constant of 40ms, the contact breaking capacity is 30W. In an AC circuit, it is 500VA (coso=0.4 ± 0.1). The long-term current passing through the contact is 5A.
4.7 Power consumption
4.7.1 Under DC rated voltage, it is �� 3W.
4.7.2 Measure circuit power consumption �� 2W at maximum thermal stability current
4.8 Delay adjustment range action: 0-9s, return: 0-9s.
Level difference: 1s Error: 10%.
4.9 The relay can withstand a voltage withstand test of 2kV, 50Hz, and 1min between different circuits. Each contact can withstand a 1kV, 50Hz, 1-minute withstand voltage test without breakdown or flashover.
4.10 The anti-interference test and insulation test of the relay comply with the ZBK-45020 standard.
4.11 The relay adopts Combiflex structure, with external dimensions shown in Figure 2 (2S12C) and installation dimensions according to Figure 6 (2S12C).

Wiring diagram behind the relay:
Application extension:
Due to the delay action and delay return time circuit in JC-13 and 14 relays, with delay action setting t1 and delay return setting t2, there are multiple applications that can be extended.
6.1 Signal triggered automatic reset
No reset button: After signal start t1, the relay starts, and after signal reset t2, the relay returns.
6.2 Manual Reset
After the signal starts t1, the relay starts, and after the hand returns, the relay returns.
6.3 Relay self resetting
The relay contacts are connected in series to the reset circuit. After the signal is activated t1, the relay starts, and after the relay acts t2, it returns.
