8-channel 5V relay module with optocoupler
8-channel 5V relay module with optocoupler for Arduino, Raspberry Pi, and microcontroller control of AC/DC devices.
The 8-Channel 5V Relay Module with Optocoupler is a high-capacity, safe solution for controlling AC or DC devices using low-voltage microcontroller signals. Operating at 5V control voltage, each relay can switch loads up to 10A, making it ideal for home automation, robotics, IoT, and industrial electronics projects.
Equipped with optocoupler isolation, indicator LEDs, and screw terminals, this module protects your microcontroller from voltage spikes while providing clear status monitoring. It is compatible with Arduino, Raspberry Pi, ESP32, ESP8266, and other microcontrollers, enabling reliable control of lights, fans, motors, and other appliances.
