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

The Dual Relay Board is an accessory to the PhidgetInterfaceKit 8/8/8. Each relay is controlled by a seperate Digital Output, and can control open or close a circuit up to 240 volts at 10 amps AC or 100 volts at 5 amps DC. The relay board does require power connection from one analog input, and so reduces the number of available analog inputs.

  • The relays are Single Pole Double Throw (SPDT)
  • The relays can switch up to 240 V AC at 10 Amps and 100 V DC at 5 Amps.
