SRD-12VDC-SL-C 5V Relay | 10A Power Relay Module for Arduino, ESP32 & Raspberry Pi

Product Description

The SRD-12VDC-SL-C 12V Relay Module is a reliable electromechanical switching device used to control high-voltage or high-current loads using low-voltage control signals from Arduino, ESP32, STM32, or Raspberry Pi.

This relay provides complete isolation between the control circuit and load, ensuring safe operation when switching devices like lights, fans, motors, solenoid valves, and appliances.
With its standard 12V coil voltage and 10A switching capacity, it’s ideal for home automation, IoT, and smart control systems.
