DF Robot 5A Relay Module

A relay is an electrically operated switch, which has a control system (also known as the input circuit) and the controlled system (also known as the output circuit), usually used in an automatic control circuit. It is actually an "automatic switch", using a small electric current to control a larger current. Therefore, the relay has the effects on the automatic adjustment, security, conversion circuit in the circuit and so on.

Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal.

The DFRobot Relay Module is a standard relay used with a controller board to interface external electrical circuits or modules. Some of the most common applications with Arduino are: Home lighting, electrical appliances of high power and other equipments. 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.
