Wittgen relay 24V DC 72067

Relay is an electrical control device that causes a predetermined step change in the controlled quantity in the electrical output circuit when the change in input quantity (excitation quantity) meets the specified requirements. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). Usually used in automation control circuits, it is actually an "automatic switch" that uses small currents to control the operation of large currents. Therefore, it plays a role in automatic regulation, safety protection, and conversion circuits in the circuit.
