This Arduino Shield is a completely newly designed that is able to control 4 relays at a time. The max switching power DC 90W or AC 360VA gives direct control by Arduino Uno/DFRduino controllers through digital I/Os with external 9V supply. With built-in Xbee socket, it can be wireless remote controlled via Xbee/bluetooth/WPM.

This arduino relay shield is an ideal solution for home automation and robotics applications.

NOTE:The Arduino board requires an external power supply to drive the xbee module and relays.

Warning:Pay special attention to the voltage that is over 38 volts.
