The Dual Relay Board allows you to control larger loads and devices like AC or DC motors, electromagnets, solenoids, and incandescent light bulbs.

Comes packaged with:

  • A 3002 – 60cm Sensor Cable

Note: This board is not suitable for switching signals. It takes at least 100mA of current to bridge the oxide layer that forms on the relay contacts, and most signals will not meet this requirement. If you need to switch signals, check out the 1017 - PhidgetInterfaceKit 0/0/8.

*Note: Switching this relay at voltages higher than 30V will result in a reduced product lifespan.

Please Note: This relay cannot be switched at its maximum AC voltage and current at the same time. Ensure that total power of the load does not exceed the switching power for the relay. For example, you can switch this relay at 277V AC and 6.3A (1750VA), or at 145V AC and 12A (1750VA), but not at 277V and 12A (3324VA).
