* Maximum contact voltage depends on the type of load - details in the documentation, tab. 7. Contact Rating.


The module allows to control the actuators consuming the current up to 10 A using the microcontroller's ports or development set (e.g. Arduino). In the system is a transistor amplifier which allows you to control the relay directly from the microcontroller's port (5 V). The relay activation is signaled by turning on of the corresponding LED.


For proper operation, it is sufficient to connect the power supply of the relay and the digital control signal. Pins are the standard goldpin straps with the pitch of 2.54 mm which allows for the connection using the popular connecting cables.


To connect to your Raspberry Pi, we recommend you to use the version with optical insulation.


Examples of application

  • Driver of lighting
  • The driver of actuators
  • Switch for electric devices, including motors

The module has three input pins VCC, GND, IN1, IN2, IN3, IN4. For the system to work correctly, you must connect the power supply of 5 V to the VCC pin, ground GND and the input signal INx.


Output pins are marked as NO - disconnected by default, NC - by default, it is connected with COM. Indicating the low status at the INx pin, switches the relay contacts and makes the connection between the COM and the NO, disconnecting the COM from the NC.
