[0002] A relay is an electrical control device. When the change in input quantity (excitation quantity) reaches the specified requirement, it causes a predetermined step change in the controlled quantity in the electrical output circuit. It has an interactive relationship between the control system (also called the input circuit) and the controlled system (also called the output circuit). Usually used in automated control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit. Relays are generally used in combination with relays, bases, and protective covers;
