A 4 channel relay shield (HCARDU0102) which conveniently and safely allows an Arduino to interface to the outside world via a set of relays. The shield will plug into an Arduino with standard headers and screw terminals for the relay contact means that no soldering is required. The relays can be individually controlled via 4 digital pins on your Arduino. An on board 5V regulator means that the relays can be powered from a power supply with a wide 7 - 12V voltage range (9V ideal). Screw terminals or a standard DC connector allow for easy connection of the power supply.

Although this board is designed as an Arduino shield it can also be used stand alone. With the addition of our PT2262/PT2272 wireless modules the relays on this board can be controlled wirelessly without the need for a microcontroller. See items HCMODU0048 & HCMODU0049.

Please note: There is an screen print error on this shield, D0 = D7, D1 = D6, D2 = D5, D3 = D4.
