Background technique

The relay is an electric control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. It has a control system (also known as The interaction between the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses small currents to control large current operations, so it plays the role of automatic adjustment, safety protection, and conversion circuits in the circuit.

Relays are composed of multiple parts. In the past, relays were assembled manually, which made the processing efficiency low.
