DFRobot Relay Shield 2.1 for Arduino
Description Completely new design capable of controlling 4 relays Compatible with Arduino UNO Rev3 Each Relay has its own test button Supply Voltage: 9V This DFRoobot Relay Shield for Arduino V2.1 is a completely new design which is capable of controlling 4 relays. The max switching power could be DC90W or AC 360VA. It could be directly controlled by Arduino/DFRduinothrough digital IOs with external 9v supply. With a built-in Xbee typesocket, it can be wirelessly controlled via Xbee/Bluetooth/WPM, making itan ideal solution for home automation and robotics purpose.
