| 3051_1 - Dual Relay Board |
Product Features
- The 3051 contains 2 relays for switching AC or DC power.
- 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.
- Powered by any device with an Analog Input.
- Controlled by any device with a Digital Output.
The Dual Relay Board allows you to control larger loads and devices like AC or DC motors, electromagnets, solenoids, and incandescent light bulbs.

You can protect your board by purchasing the 3820 - Acrylic Enclosure for the 3051.
Note: All relay contacts will slowly oxidize over time, depending on their construction. When the relay is switched, a certain amount of electricity is required to break through the oxide layer. The relays on the 0/0/4 have a minimum switching current of 100mA @ 5VDC, and therefore are not suitable for switching signals.
If you are looking for a product to do signal switching see 1017 PhidgetInterfaceKit 0/0/8.
We also have a 4-Relay board that can plug directly into your PC. See the 1014 – PhidgetInterfaceKit 0/0/4.
