The 5V 1-Channel Relay Board is a compact and reliable module designed to control high-voltage devices using low-voltage digital signals from microcontrollers like Arduino, Raspberry Pi, and other development boards. It allows you to safely switch AC or DC loads such as lights, fans, and motors using a simple 5V input signal.
Features:
Relay Ratings: Capable of switching up to 250VAC/10A and 30VDC/10A, suitable for both AC and DC devices.
Trigger Current: Requires a low trigger current of just 5mA for energy-efficient operation.
Operating Voltage: Functions on a 5V TTL signal input.
Mounting Holes: Equipped with four 3.1mm holes for convenient mounting.
Screw Terminals: Includes C, NC, and NO terminals for easy wiring.
Flyback Diode: Built-in diode safeguards the microcontroller from voltage spikes during switching.
LED Indicators: Visual ON/OFF status indication for the relay.
Protection Circuit: Uses a BC547 transistor to safely drive the relay.
Microcontroller Compatibility: Fully compatible with Arduino and similar development boards.
Versatile Applications: Ideal for controlling fans, lights, solenoids, motors, and more.
