Moduł przekaźników 8 kanałowy


The module allows to control the actuators consuming the current up to 10 A using the microcontroller's ports or any starting set (including Arduino, Rasbperry Pi and STM32Discovery). Optoisolation seperates the control signal from the part associated with the power of relay, thereby providing safety of the controlling system's work.


The product is compatible with Arduino

For relay control, a digital control signal from leads of the Arduino is enough.



For proper operation, it is sufficient to connect the power of relay's coil and the digital control signal. Leads are the standard strap goldpin with pitch of 2.54 mm which eneable the connection by the connecting cables.

 Moduł przekaźników 8 kanałowy.

The relay has the following leads

  • VCC - power of optoisolation
  • GND - mass of system
  • IN1 ... IN8 - control inputs of relays, activated by high state
  • Jumper COM GND - connect the system masses with the mass of optoisolation
  • Connectors KF (ARK) - the relay contacts are connected in accordance with the pattern on plate of the module.


Examples of application

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



  • Channels 8
  • Interface Digital I / O
