This is a small and easy to use 2 channel relay board that operates on 12V. Use it to control two 240V power appliance directly from microcontrollers or low voltage circuits. Perfect for switching 240V appliances - lights, fans, etc, and even high power motors at lower voltages.
The board uses high quality relays, which can handle a maximum of 7A/240 V AC or 7A/24V DC. Each relay has all three connections - Common, Normally Open, Normally Closed brought out to 3 pin screw terminals which makes it easy to make and remove connections. The board has a power indication and relay status LEDs to ease debugging. The board can accept inputs within a wide range of voltages from 4V to 12V.
Power input and relay control signals are brought to header pins on the board. Hence, the board can be easily interface with our development boards using our female to female jumper wires.
