[signal relay]DXM-2A type signal relay

2026-6-16 11:17:45

Application of DXM-2A Signal Relay
DXM-2A signal relay is used in DC operation protection and automatic control circuits as an action indicator for remote reset.

Working principle and structure of DXM-2A signal relay
2.1 The relay is a reed switch type relay. It consists of a reed switch, a working winding, a release winding, a self-locking permanent magnet, and an indicator light. When the working winding is conducting, the magnetic field generated by the coil is of the same polarity as the permanent magnet placed inside the coil, and the magnetic flux is superimposed, causing the contacts inside the reed switch to close and the red signal light to turn on. After the working winding loses power, the contacts are held by permanent magnets. When the winding is released for conduction, the magnet generated by the coil has the opposite polarity to the permanent magnet, causing the contact to return and the signal light to turn off.
2.2 Relays have two structures:
2.2.1 Protruding plug-in structure. Adopting Aji JK-5 shell (horizontal), its outline and opening diagram are shown inAppendix IThe internal wiring of the relay is shown in Figure 1.

[signal relay]JX-4A,JX-22D,JX-32D type secondary display signal relay

2026-6-16 11:16:27

Purpose:
JX-4A, JX-22D, and JX-32D static signal relays are derivative products of the JX series static signal relays produced by our company, suitable for use as signal indicators for relay protection actions in DC operated protection circuits. Especially suitable for signal indication that reflects two consecutive actions.
Features:
2.1 Fast action speed, able to respond promptly to switch on/off status.
2.2 The starting circuit and the reset circuit are independent of each other, and the starting amount can be voltage or current.
2.3 The excitation amount for the start-up and reset circuit can be continuous or pulsed (with a width greater than 50ms).
2.4 Manual and remote electrical reset can meet the requirements of unmanned operation.
2.5 JX-22D and JX-32D models have 5 output contacts, among which two empty contacts and one active contact reflect the first action state, and the other two empty contacts reflect the second action state. The JX-4A model has 4 sets of dynamic contact points, which can hold 3 sets of dynamic contact points, 1 set of instantaneous contact points, or 4 sets of holding contact points.
The indicator lights and contacts on the 2.6 relay panel can reflect two consecutive action states and maintain them, and can be manually or electrically reset in one go.

JX-4A, JX-22D, JX-32D type secondary display signal relay model name:

Working Principle:
The relay consists of a starting circuit, a return circuit, a power circuit, a two action discrimination circuit, a momentary relay, a first action relay, and a second action relay. When the starting amount (voltage or current) is added, the instantaneous relay, primary action relay, and secondary action relay are excited by the action coil, and the relay is activated. When the starting quantity is removed, the instantaneous relay returns instantly. Due to the holding function of the circuit itself, only when an external reset voltage is added or the manual reset button is pressed can the primary and secondary action relays be reset to their original state.
The power circuit is used as the working power supply for static relays. When the relay operates continuously twice, the secondary action discrimination circuit causes the signal light to display the indication of primary and secondary actions.

Instructions for using JX-4A, JX-22D, JX-32D type secondary display signal relays:
6.1 When using this relay, a DC auxiliary voltage needs to be applied, which can be taken from the control bus KM+and KM -, or from the signal bus XM+and XM -. When connecting DC voltage, pay attention to whether the rated voltage matches, and pay attention to the polarity of the voltage. If the polarity is connected incorrectly, the relay will not work, but it will not damage the relay.
6.2 During normal operation, manual or electrical reset should be performed to turn off the action indicator light on the panel.
In the 6.3 relay wiring diagram, the power supply (+) and power supply (-) are connected to the auxiliary power supply. The reset (-) terminal of JX-22D and JX-32D relays is connected to the negative terminal of the auxiliary power supply through an external reset contact. The JX-4A relay has no electrical connection between the reset circuit and the auxiliary power supply or starting circuit, so the use of the reset power supply is very flexible. KM+and KM -, XM+and XM - can all be used as reset power supplies, and the reset contacts can be connected to either the reset (+) or reset (-).
If the reset voltage of JX-4A relay is taken from the DC auxiliary power supply, the relay reset (+) can be short circuited to the power supply (+), and the reset (-) can be connected to the auxiliary power supply (-) through an external button or contact. It is also possible to short-circuit the reset (-) to the auxiliary power supply (-), and connect the reset (+) to the auxiliary power supply (+) through an external button or contact.
There are two signal indicator lights on the 6.5 relay panel, which respectively indicate the signal for primary and secondary actions. When the relay is first activated, the primary indicator light will turn on, and the instantaneous relay and the primary action relay will activate. After the excitation amount is removed, the instantaneous relay returns. Due to the circuit's holding function, the primary action relay still maintains its operating state and the primary indicator light remains on. When the relay is not manually or electrically reset and the starting quantity is added for the second time, the instantaneous relay and the secondary action relay will act, and the secondary signal indicator light will light up. After the two indicator lights are lit, they will only turn off when the starting amount is removed and the relay is manually or electrically reset.
