Dual Relay Board

This board has 2 SPDT mechanical relays rated at 240VAC/10A or 100VDC/5A.

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

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.

Comes Packaged with:

3002 - 60cm Sensor Cable
