Relay function
1) Expanding the control range: For example, when the multi-contact relay control signal reaches a certain value, it can switch, disconnect, and turn on multiple circuits at the same time according to different forms of the contact group.
2) Amplification: For example, sensitive relays, intermediate relays, etc., with a very small amount of control, can control a very high power circuit.
3) Integrated signal: For example, when a plurality of control signals are input into a multi-winding relay in a prescribed form, the comparison is integrated to achieve a predetermined control effect.
4) Automatic, remote control, monitoring: For example, the relay on the automatic device together with other electrical appliances can form a program control circuit to achieve automatic operation.
