Relay Shield for Arduino
IntroductionThe DFRobot Relay shield is capable of controlling 4 relays.  The max switching power could be DC 90W or AC 360VA. It could be directly controlled by Arduino/DFRduino through digital IOs with external 9v supply. With buildin xbee type socket, it can be wirelessly controlled via Xbee/bluetooth/WPM.  Make it an ideal solution for home automation and robotics purpose.Specification- Up to 4 Relay with photo-coupled circuit- Contact Rating  3A AC 120V / DC 24V- Max Switching Voltage  AC 240V / DC 60V- Max Switching Current  5A- Max Switching Power  AC 360VA / DC 90W- Electrical Life (Min)  100,000 Operations- Mechanical Life (Min)  10,000,000 Operations- Safety Standard(relay)  UL cUL TUV CQC- Coil Working Voltage  9VDC- Weight  165g- Working temperature  -30℃ to +85℃- Working temperature  40% - 85%Shipping ListRelay Shield for Arduino (1 unit)
