Description
The five-volt two-channel relay module is designed to control two power loads via Arduino or other controllers.
To use the relay module, you need to connect a controlled device to it. Then you need to connect 5V power to the VCC and GND pins of the module. Then it is necessary to connect a microcontroller, computer or other control device to the control terminals IN1 - IN2 of the relay module and start working.
The relay module has two interfaces - for connecting the control microcontroller and for connecting controlled devices to the relay. A 4-pin connector is used to connect the relay module to the control device. Contacts GND and VCC for connecting the supply voltage 5V, outputs IN1 - IN2 for connecting the control signal.
To connect the load to the relay, there are 6 screw contacts on the board, 3 for each relay.
The relay module can be powered both from the control controller and from external power sources.
If full galvanic isolation is required, connect VCC to the Arduino's +5V output, but do not connect GND. Remove the VCC - JDVCC jumper. Connect separate +5V to the JDVCC and GND pins on the board to power the transistors and relay coil.
