A relay module is an electronic module used to control and switch circuits. It usually includes one or more relays, and corresponding control circuits.
Relay is a kind of electromagnetic switch, it can control the circuit through the electromagnetic force. ACC-5595-208 When the coil of the relay is energized, it creates a magnetic field that attracts the iron core, which makes the relay contacts close or break. By controlling the coil of the relay, the circuit can be controlled and switched.
Relay modules typically have multiple input channels and output channels, ACC-5595-208 each of which can be connected to one or more relays. By controlling the signal of the input channel, the corresponding relay can be controlled on and off, so as to realize the control and switch of the output channel.
Relay modules are widely used in automation control systems, power systems, home automation and other fields. They can be used to control lights, motors, solenoid valves and other equipment to achieve automatic control and remote control.
