Product Description

Now available from Tronixlabs Australia is this useful four relay shield for Arduino. Each relay is opto-isolated from the Arduino (or compatible!) digital outputs - and can switch up to 24V DC at 3A or 230V AC at 1.5A.

Perfect for switching larger DC loads with your Arduino, or controlling lighter AC loads such as lights and so forth. Each relay can be activated with a digital output, and DIP switches are fitted to the shield so you can manuall control or over-ride the relays if need be. 

If you need to switch higher currents, please consider our relay modules or SSRs


  • Shield operating voltage: 7~12V
  • Current: 8~250mA
  • Relay Switching Voltage: Max 35V
  • Relay Switching Current : Max 2A
  • Frequency Response: -1~1dB
  • Switching Power: Max 70W
  • Relay Life: > 100000 cycles

Using your relay shield:

Please apply some insulation tape over the USB socket of your Arduino as it may come in contact with the shield. 

For example code and schematics, please see the shield Wiki page
