DFR0144 Relay Shield for Arduino

DFR0144 DFRobot Relay Shield for Arduino

One of the most interesting projects for your boards is perhaps being able to control High power devices like Lamps, water pumps, garage doors and so on. But interfacing with high power and AC is quite a dangerous task when building the circuitry. Relays allow for interfacing an external electrical circuit like a switch. With relays you can now connect external circuit or devices directly to your Arduino.

DFRobot Relay Shield  V2.1 is a completely new design which is capable of controlling 4 relays at a time. The max switching power DC 90W or AC 360VA gives direct control by Arduino/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 relay shield is an ideal solution for home automation and robotics purposes.

Features:

• Compatible with Arduino UNO Rev3
• Each Relay has its own test button to test the connection
• Standard DFRobot 3 Pin out
• XBee I/O direct control
