If you want to drive an inductive load, or AC, or DC, or mysterious load, you can't beat a relay. It just works. It isn't fast, but it sure is powerful.

This shield plugs directly onto a standard Arduino footprint device, and you have 4 relays at your command.

Note: Please ensure the back of the board is insulated before attaching to an Arduino main board. The green terminal blocks can short out against a metallic surface like the top of the USB connector!

Specifications:

Operating Voltage 5V
Operating Current 130mA
Max Switching Current 3A
Power voltage: 4.75~5V;
Power consumption (at 5V): 180mA;
Limit relay operation to no more than 30 cycles per minute

70 x 54 x 26mm (2.76 x 2.13 x 1.02")
Weight 1.41 oz (40 g)
