Product Description

Controlling larger systems is easy with this eight relay module. The relays can be opto-isolated from the control circuit. The inputs are 3.3V tolerant however the control circuit requires 5V - so it can be controlled from your Arduino, Arduino Due, Raspberry Pi, or other 5V or 3.3V development board along with TTL outputs and so on. Please note that control lines are active LOW (so a HIGH signal turns a relay off, a LOW turns it on)

Specifications

  • Relays - 250V AC 10A or DC 30V 10A
  • Size: 140mm X 55mm 

Instructions:

Review the side of the relay board as shown below:

If you want to have the relays isolated from your control circuit:

  1. Remove the blue jumper from the board.
  2. Connect a 5V power supply with at least 160 mA current ability to the GND and JD-Vcc pins on the right-hand side of the board. This is for relay coil power. 
  3. Connect 5V from your microcontroller board (e.g. Arduino 5V pin) to the Vcc pin on the right-hand side of the input pins.
  4. You don't need to run a GND wire from the microcontroller board - do not connect this to the GND side
  5. Connect a line from each digital output on your microcontroller board or other circuit to pins IN1~8 of the input pins respectively. Each of these will trigger a relay. The inputs are active low - so a high signal (3.3~5V) turns a relay OFF, 0V turns it ON.

If you do not want to have the relays isolated from your control circuit:

  1. Connect a 5V power supply with at least 160 mA current ability to the GND and Vcc pins that are on each end of the input pins. Each relay coil draws up to 20mA of current.
  2. Connect the blue jumper as shown in the photo above.
  3. Connect a line from each digital output on your microcontroller board or other circuit to pins IN1~8 pins respectively. Each of these will trigger a relay. The inputs are active low - so a high signal (3.3~5V) turns a relay OFF, 0V turns it ON.
