Relay is an automatic switching device with isolation function, which has wide applications in remote control, telemetry, communication, automatic control, mechatronics, power electronics, and other fields. Relays usually have an induction mechanism (input component) that can reflect specific input parameters (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.); Equipped with an executing mechanism (output unit) that can control the “on” and “off” of controlled circuits; There is also an intermediate device (driving part) between the input and output parts of the relay, which is used for coupling, separating, functional processing, and driving the output components of the input quantity
