Product description
4-Channel 5V DC Relay Module Extension Board With Opto-Isolated Protection Relay Shield V1.3
4 channel 5V Relay module extension board Relay Shield V1.3 for arduino compatible
The Relay Shield is an Ard uino compatible smart module with 4 mechanical relays providing an easy way to control high voltage. The max switching power is 70W DC. It can be directly controlled by Ard uino through digital IOs with external 9V supply. With the XBee form socket and 315/433MHz RF module interface, the Relay shield can be remotely controlled, making it easy to use in robotics, industry control, smart houses etc.
Note:
Take care the pins on the Shield should not be touched with USB connector of Ard uino UNO when they are connected .
Features
Ard uino uno, Ard uino Mega,
4 mechanical relays with photo-coupled circuit
