The module allows to control the actuators consuming the current up to 10 A using the microcontroller's ports or any development kit (including ArduinoRaspberry Pi and STM32Discovery). Optical insulation seperates the control signal from the part associated with the power of relay, thereby providing work safety of the management system.


The product is compatible with Arduino

For relay control, sufficient is a digital control signal from the pins of the Arduino.



For proper operation, it is sufficient to connect the power of the relay coil and the digital control signal. Leads are the standard goldpin strips with the pitch of 2.54 mm, which enables connection using the popular connecting cables.

The relay has the following pins

  • VCC, DC+- power supply of the optocoupler
  • GND,DC- - ground of the system
  • IN1 ... IN6- control inputs of the relay are activated by the the low status
  • Connectors KF (ARK)- the relay contacts are connected in accordance with the pattern on the board of the module.


Examples of application

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

The system perfectly fulfills the described task
Bartłomiej 30.09.2022 Confirmed purchase Translated review
Good relays. A small downside is the delicacy of the cable connection terminals, you need to tighten the screw carefully.
