4-channel 5V optocoupler relay module
4-channel 5V optocoupler relay module for Arduino, Raspberry Pi, and microcontroller control of AC/DC devices.
The 4-Channel 5V Optocoupler Relay Module is a versatile and safe solution for controlling AC or DC devices using low-voltage signals from microcontrollers. Operating at 5V control voltage, it features four relays, each capable of switching loads up to 10A, making it ideal for home automation, robotics, and DIY electronics projects.
Equipped with optocoupler isolation, indicator LEDs, and screw terminals, this module ensures safe operation while protecting your microcontroller from voltage spikes. It is compatible with Arduino, Raspberry Pi, ESP32, ESP8266, and other microcontrollers, enabling reliable control of lights, fans, motors, and other appliances.
