1 Channel 12V Relay Module for Microcontroller and Automation Projects (12V DC Coil)

The 1 Channel 12V Relay Module is an electromechanical switching module designed to control electrical loads using a low-voltage digital control signal. It uses a 12V DC relay coil and an onboard driver circuit to switch connected AC or DC loads. It is suitable for microcontroller projects, embedded systems, home automation, and general-purpose electrical control applications. Trigger voltage, contact rating, and isolation features depend on the specific module variant.
