The module allows the control of the actuators consuming a current of up to 10 A using the microcontroller’s port or any development kit, for example, Arduino and Raspberry through the low or high status selected by the jumper. Optoinsulation separates the control signal from the part associated with the relay’s power, there by providing work safety for the management system.


It is sufficient to connect the power to the relay coil and the digital control signal to the pins of the screw ARK connectors, which are linked by any cables with the insulation stripped at the ends, for appropriate functioning.


  • DC+– power supply of system
  • DC– ground of the system
  • IN1, IN2, IN3, IN4, IN5, IN6, IN7, IN8 – control inputs of the relays activated by the high or low status
  • Jumper– to change the status of the activation of the relay:
    • The H position– the specified channel is activated by the high-status
    • The L position– the specified channel is activated by the low-status
  • Output relay contacts:
    • NC – COM is shorted by default
    • COM– shared, shorted with NC or NO, depending on the control signal
    • WELL– splayed by default


  • Channels: 8 Relays
  • Vcc and Relay (input trigger) Voltage: 5V
  • Relay Trigger Current(Optocoupler trigger): 2 to 5mA
  • Relay Trigger Low Voltage: 0 to 1.5V
  • Relay Trigger High Voltage: 3 to 5V
  • Relay Output Current: 10A at 250VAC, 10A at 30VDC
  • Input Type: Opto Isolated inputs
