This is a 8 channel relay board operates on 5V. Can be used directly to control 240V power appliance from most of the microcontrollers and other control system circuits. Perfect for switching 240V appliances like lights, fans, etc.

The board has a high quality relay, which can handle a maximum of 10A @ 120V or 7A @ 240V AC, 7A/24V DC. Each Relay has three connections – Common – C, Normally Open-NO, Normally Closed-NC brought out to 3 pin screw terminals which makes it easy to make and remove connections. The board has a power indication and a relay status LED to ease debugging. Power input and relay control signals are brought to header pins on the board.
