Relay Shield v1.1 (4-Channel 35V 2A)
The Relay Shield is an Arduino compatible smart module with 4 mechanical relays to provide an easy way to control high voltage. The max switching power is 35VDC 70W for each channel. It can be directly controlled by Arduino through digital IOs with external 9V DC supply or manually through DIP selector switches.
Pin 4-7 on the Arduino Uno is used.
Note: An external power of 9V is required.
Caution: Please place 2 layers of electrical tape on top of the Arduino's usb connector to prevent the relay shield from making contact with the Arduino Uno. Do not operate voltage more than 35V DC.
