The Working Principle Of The Relay Module

The relay is an electronic control component. It has an automatic control system (also known as an input control loop) and an automatically controlled system (also known as an output control loop). It is generally used in automatic control circuits. It actually It is a "control switch" that uses a smaller amount of current to control a large amount of current. Therefore, it plays the functions of automatic adjustment, safety protection, and circuit conversion in the circuit.
When the relay control module is working, the solenoid valve is plugged in, sucking the armature down to make D and E touch, and the circuit is closed during operation. When the solenoid valve is powered off, it loses magnetism, and the torsion spring pulls up the armature and disconnects the working circuit. Therefore, a relay is a switch that uses a solenoid valve to control the conduction of the circuit during operation.
The benefits of using relays to control circuits: use low voltage to control high voltage; long-distance control; automatic control system. The relay module is an automated electrical switch that works by the magnetic effect of electric current.
