NOTE: Place 2 layers of electrical tape on the top of the Arduino's usb connector. This will prevent the relay shield from making contact. Do not operate voltage more than 35V DC.

Shield Interface Description

Relay Shield V2.0 terminal connections description

  • Digital 4 – controls RELAY4’s COM4 pin (located in J4)
  • Digital 5 – controls RELAY3’s COM3 pin (located in J3)
  • Digital 6 – controls RELAY2’s COM2 pin (located in J2)
  • Digital 7 – controls RELAY1’s COM1 pin (located in J1)

J1 Interface/Terminal Pin Description:

  • COM1 (Common Pin) : The relay pin controlled from the digital pin.
  • NC1 (Normally Closed): This terminal will be connected to COM1 when the RELAY1 control pin (Digital 7 I/O pin) is set low and disconnected when the RELAY1 control pin is set high.
  • NO1 (Normally Open): This terminal will be connected to COM1 when the RELAY1 control pin (Digital 7 I/O pin) is set high and disconnected when the RELAY1 control pin is set low.

Terminals J2-4 are similar to J1 except that they control RELAY2-RELAY4 respectively. 

Note: Only four Arduino Digital I/O pins, pins 4-7, are required to control the four different relays. Additionally the 5V and two GND Arduino pins are also required to power up the Relay Shield.
