5V 4Ch Relay Module with Optocoupler is a small and easy to use. Significantly it can be used to control one 240V power appliance directly from Arduino, Raspberry Pi, and other microcontrollers or low voltage circuits. Perfect for switching 240V appliances lights, fans, etc, and similarly even high power motors at lower voltages.
