Function: A relay is an automatic switching component with isolation functionality, serving as an "automatic switch" that uses small currents to control the operation of larger currents. Therefore, it plays roles in automatic regulation, safety protection, and circuit conversion within electrical circuits. 2. Working principle: A relay is an electrical device that gradually alters the control quantity in a circuit when changes in the input quantity meet specified requirements. It interacts between the control system and the controlled system (also referred to as the output circuit).
