Description Single Channel 12V Relay Board: A relay is an electrically operated switch. Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on or off so relays have two switch positions. 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 board has ONE relay which works on 12V but the input signal can come directly from microcontroller output working at 3V or 5V to control relays. Each relay can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of relay is indicated by the RED Led. This is a Single channel relay board operates on 12V. Can be used directly to control 240V power appliance from most of the microcontrollers and other control system circuits. Perfect for switching 240V appliances like lights, fans, etc. The board has a high quality relay, which can handle a maximum of 10A @ 120V or 7A @ 240V AC. Each Relay has three connections - Common - C, Normally Open-NO, Normally Closed-NC brought out to 3 pin screw terminals which makes it easy to make and remove connections. The board has a power indication and a relay status LED to ease debugging. Power input and relay control signals are brought to header pins on the board. Features: Selectable Port Input Mounting Supports Provided Relay Switching Output Suitable for 7A @ 250Vac or 10A @ 120Vac LED Indication of Relay ON. Power Indication LED. Direct input from 3-5V Microcontroller for relay control. Output terminal for relay contacts. Provision of male header for wire connection. Powered from external 12V or from male header. Note: It is important that microcontroller share ground with relay board along with other control signals else it will not able to control relay.
