The DFRobot Relay shield V2.1 is capable of controlling 4 relays. The max switching power is DC 90W or AC 360VA. It is possible to control the Relay shield through Arduino/DFRduino using digital IOs with external 7 to 12V supply. With the built in xbee socket, it can be wirelessly controlled via Xbee/bluetooth/WPM. This makes it an ideal solution for automation and robotics.
