1 Application range

This series of intermediate relays are mainly used in the circuit of switch tripping, closing position monitoring, and power supply monitoring. It is especially suitable for the new 380V system imported switch circuit. This product has the characteristics of low starting current, high starting coil internal resistance, and common working voltage of AC and DC. .

2 Model definition

When the relay is equipped with M, the relay will act instantaneously when the power is turned on. When the power supply is not disconnected, the pulse delay will return automatically, and the delay time can be set (that is, the contact action time of the relay is a pulse time with adjustable width); When the time has not reached the set time, disconnect the power supply, and the relay will return instantly.

When the relay is equipped with S, the relay will act instantaneously after power-on, and will return with a delay after power-off. The delay time can be set.

3 main performance
