JX-13 type signal relayDetailed product description：

Purpose:
JX-13 signal relay is used in DC operation protection circuits as a signal indicator. Relays are operated by current or voltage, with light signals, magnetic holding, manual or electrical reset, ensuring good reliability.

Relay model name:
Example: The ordering code for a signal relay with an auxiliary DC working voltage of 110V and a rated current of 0.5A is JX-13-0.5A-DC110V.




Working Principle:
The relay is composed of components such as optocouplers and resistors to form a sampling and detection circuit. When the measured signal reaches a certain value, the optocoupler is turned on, and the signal is amplified by an operational amplifier to drive the output circuit of the subsequent stage, causing the output relay to act. And it is self held by the self holding circuit. After the start circuit signal disappears, the relay is still in the operating state. The relay can only return after pressing the reset button or applying a reset voltage at the reset terminal.
