1 CHANNEL 12V RELAY

This single-channel relay module commonly used a board in order to control high voltage, high current load. This  12v relay interface board with screw terminals interfaced with any microcontrollers, Arduino, pic, etc. This is a prominent and high-quality relay board that can handle a maximum of 15A @ 125V and 10A @250V AC. This consists of mainly three connections: common(c), normally open (NO), normally closed (NC), and connected to the screw terminals which makes the wiring much easier. This relay circuit safe drove by BC 547 transistor hence protects the microcontrollers from the relay circuit.

There exist 2 LED on the relay module in which red indicates the status of relay and green for power. When the input digital signal remains high, the relay switched ON (closed), else switch is OFF (opened). This module can control various applications and equipment with a large current which is compliant with international safety. In this relay module, the Power input and relay control signals  brought to header pins on the board. Thus, the board can be easily interfaced with our development boards using female to female jumper wires.

This Relay circuit defined as a small and easy to use 1 channel relay board that operates on 12V. This single-channel relay module widely used to control one 240V power appliance directly from Arduino, Raspberry Pi, and other microcontrollers or low voltage circuits. In short, it Perfect for switching 240V appliances – lights, fans, etc, and even high power motors at lower voltages.
