This 8 Channel Relay Module is a great way to automate common tasks around the house. You can set up your own home appliance control using this relay module and an Arduino. This relay module takes a control signal between 2.5 and 5 Volts and controls a DC or AC signal, either closing the circuit when the control signal is on or opening the circuit when the control signal is off. This module is perfect for common Arduino-controlled automation applications.


  • Suitable for home appliance control
  • 2.5V-5V TTL control signal (such as the signal from an Arduino)
  • Can control DC or AC signals
  • Can control a 220V AC, or 30 V DC load up to 10 Amps
  • Each Relay has a normally open and normally closed terminal so you can just choose whichever you need
  • Each of the 8 channels is isolated for added reliability
  • LED Indicators to show when each of the 8 relays are on



  • Input Signal Voltage:
    • 0V - 0.5V : Relay ON
    • 2.5V - 5V : Relay OFF
  • Input Signal Current: 0.1 mA @ 2.5V, 0.18 mA @ 3.3V, 0.35mA @ 5V
  • Driver Current: 15 - 20 mA
  • Total Max Current Draw (all relays on) : 400 mA
  • Supports External Relay Power Supply (By leaving the jumper on the board you will use Vcc as the power for the relays. To enable external relay power, such as when you're worried about having too much current draw because your Arduino is also connected to other current drawing devices, remove the jumper from the pins VCC and JD-VCC and connect your external power supply to the GND and JD-VCC pins.)
  • Dimensions: 14 cm x 5.5 cm / 5.5" x 2.2"
