Ordering instructions

The relay model and specification must be indicated when ordering 、 Structural form code 、 Wiring mode before or after the board 、 Quantity and other requirements .

Two position relay , As the name suggests, it means that the relay has two positions , At the same time, it can keep itself in both positions . actually , The two position relay is a magnetic holding relay with two coils .

coil A After power on , Relay contacts act , Even if it loses power , The contacts do not return ; coil B After power on , Relay contact return , Even if it loses power , The contacts will no longer act . in other words , If the contact position of the two position relay is reversed , There must be a coil live .

Two position relay is common in secondary circuit of substation , Mostly used to maintain status 、 In the circuit with high reliability requirements . Such as voltage switching circuit of double bus connection and voltage parallel circuit .
