A Relay module (english name: Relay) is an electric control device, and is an electric appliance that generates a predetermined step change in a controlled variable in an electric output circuit when a change in an input variable (excitation variable) meets a predetermined requirement. It has an interactive relationship between a control system (also called an input loop) and a controlled system (also called an output loop). It is commonly used in automated control circuits, which are actually a "recloser" that uses low current to control high current operation. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like.
