What Is The Function Of Solid State Relay?

The functions of solid state relays are switching and protection circuit functions, as follows:
switch function. By adding a control signal to the input terminal of the solid-state relay, the output terminal can change from the off state to the on state (it will be in the blocking state when there is no signal), thereby controlling a larger load.
Protection circuit function. Solid state relays can be used as protection devices for short circuit protection, overload protection, overcurrent protection, overheating protection and other circuits.
In addition, solid-state relays also have the advantages of good anti-corrosion and moisture-proof performance, good isolation performance, low noise, and long life. Therefore, they are widely used in industrial automation control, computer peripheral interface equipment, electric furnace heating systems, cooked control machinery, remote control machinery, motors, solenoid valves, and It is widely used in signal lights, flashers, stage lighting control systems, medical equipment, copiers, washing machines, fire security systems and other occasions.
