This is a high quality 8 channel relay board that works on 5V. Use it to control power appliances directly from microcontrollers or low voltage circuits. Perfect for switching 240V appliances – lights, fans, etc, and even power hungry motors.
High quality relays are used, 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. Each relay has an LED to indicate its status, which helps during debugging. The board can accept inputs withing a wide range of voltages from 3.3V to 5V.
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. The power input for this board can also be provided through the onboard DC Barral Jack. Hence, power adapters can also be used to directly power this board.
