The module allows to control the actuators consuming the current up to 10 A using the microcontroller's ports or any commissioning set (includingArduino,Raspberry PiandSTM32Discovery). Optical isolation 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 leads 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 standardgoldpinstrips with the pitch of 2.54 mm, which enables connection using the popularconnecting cables.

The relay has the following leads

  • VCC- power of optical isolator
  • GND- mass of the system
  • IN1 ... IN8 - control inputs of the relays, activated by the low state
  • Jumper COM GND- connects the system masses with the mass of optical isolators
  • KF Connectors(ARK)- the relay contacts that are connected in accordance with the pattern on the board of the module.

Examples of application

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