This is a single channel relay board with one 24 volts high current relay. It is an ideal board to control & switch high current loads like a fan, lights, low power heater coils. It not only provides switching but also provides isolation between the power device and your micro-controller. Devices up to 5 Ampere can be switched using this relay.
This relay module has an onboard driver and a led to indicate the Relay Status (ON/OFF). Since this Relay board has an onboard driver transistor to provide the relay with the necessary holding and latching current these relays can work with any microcontroller, Arduino, Intel Edison Boards, Beagle-bone & Raspberry pi as well.. Featured By RoboticsBD.
