The 1-Channel 5V Relay Control Board Module is designed for controlling high-power devices with low-voltage microcontrollers. Featuring an optocoupler for signal isolation, it allows safe switching of AC and DC appliances, including motors, lights, and solenoids. This module is perfect for use with Arduino, Raspberry Pi, ESP8266, and other microcontroller systems.
Features:
High Power Rating: Switches AC loads up to 250V @ 10A and DC loads up to 30V @ 10A
5V Operating Voltage: Ideal for 5V microcontroller systems like Arduino
Optocoupler Isolation: Provides electrical isolation between the control signal and the load, ensuring protection
Low Trigger Current: Compatible with TTL logic (triggered by microcontroller pins)
LED Indicators: Clearly shows ON/OFF status of the relay
Screw Terminals: Easy to connect Common (COM), Normally Open (NO), and Normally Closed (NC) terminals
Flyback Diode Protection: Protects microcontroller from voltage spikes when switching inductive loads
Mounting Holes: Pre-drilled for easy installation and integration into projects
Wide Compatibility: Works with Arduino, Raspberry Pi, ESP32, ESP8266, and other platforms
