4-channel 12V relay module with optocoupler isolation
4-channel 12V relay module with optocoupler isolation for Arduino, Raspberry Pi, and microcontroller control of AC/DC devices.
Description
The 4-Channel 12V Relay Module with Optocoupler Isolation is a robust solution for controlling high-voltage AC or DC devices using low-voltage microcontroller signals. Each of the four relays can handle loads up to 10A, making it ideal for home automation, robotics, and industrial electronics projects.
Featuring optocoupler isolation, indicator LEDs, and screw terminals for secure connections, this module ensures safe operation while protecting your microcontroller from voltage spikes. It is compatible with Arduino, Raspberry Pi, ESP32, ESP8266, and other microcontrollers, providing reliable control for lights, motors, fans, and other appliances.
