The modular design makes it easy to integrate with a controller board. The Relay integrates a status LED, in order to acknowledge visually it's status ON or OFF. It can be controlled through the digital IO port, with a simple HIGH or LOW on Arduino compatible boards. Other boards will work requiring same voltage level. Other usages include control of solenoid valves, lamps, motors and other high current or high voltage devices.
