Function and Usage
The contact switching current can reach 16A, 32A; AC and DC specifications are complete; it meets the requirements of GB/T 21711.1 standard; the NJMC1 pulse relay is a mechanical bistable relay that changes the contact state by inputting a pulse signal. Therefore, compared to ordinary relays that require continuous power supply when the armature closes, the pulse relay has the characteristic of low power consumption.
