Automatic full-time composition program control available safety relay.

1) Expand the control range: For example, when the control signal of a multi-contact relay reaches a certain value, you can switch, break, and connect multiple circuits at the same time according to different forms of contact groups.

2) Amplification: For example, sensitive safety control relays, intermediate relays, etc., can control a circuit with a large power with a very small control amount.

3) Integrated signal: For example, when multiple control signals are input to a multi-winding relay in a prescribed form, they will achieve the predetermined control effect through comparative integration.

4) Automatic, remote control, and monitoring: For example, the relay on the automatic device and other electrical appliances can form a program control circuit to realize automatic operation.
