JX-22,JX-32 type signal relayDetailed product description：

Purpose:
JX-22 and JX-32 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.
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 has four output contacts, one of which is an active contact that can directly connect to the light plate, and the other three are empty contacts.
2.6 Relay contacts can be maintained.

Relay model name:



Working Principle:
When the starting amount (voltage or current) is added, the coil of the relay is excited and the relay is activated. After the starting quantity is removed, due to the circuit's inherent holding function, the relay can only be reset to its original state by adding an external reset voltage or pressing the manual reset button. Allow the relay to start again.

Usage:
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. Due to the fact that the reset circuit has no electrical connection with the auxiliary power supply and starting circuit, the use of reset power supply is very flexible. KM+and KM -, XM+and XM - can all be used as reset power supply, and the reset contact can be connected to either the reset (+) or reset (-).
