What are the functions of Relays?:
1) expand the scope of control: for example, when the multi contact relay control signal reaches a certain value, it can change, disconnect, turn on the multiplexer circuit according to the different forms of the contact group.
2) amplification: for example, sensitive relays, intermediate relays, etc., with a very small amount of control, you can control a large power circuit.
3) integrated signal: for example, when a plurality of control signals are input into a multiple winding relay in accordance with the prescribed form, the desired control effect is achieved by comparison.
4) automatic, remote control, monitoring: for example, the relay on the automatic device, together with other electrical appliances, can form a program control circuit, so as to realize automatic operation.
