1-Channel 12V Relay Module Active Low Trigger

1-Channel 12V Relay Module Active Low Trigger

The 1-Channel 12V Relay Module (Active Low) allows easy control of a single electrical load using a low-voltage digital signal. It operates at 12V DC input voltage, making it suitable for microcontrollers, embedded circuits, and automation systems that require 12V triggering.

This relay uses an active low input, meaning it switches when the input signal goes low. It includes an opto-isolator for protection and a flyback diode to suppress voltage spikes, ensuring safety for sensitive controllers.

The module supports both AC and DC loads up to 10A, making it suitable for applications in home automation, robotics, IoT devices, and industrial projects that require safe and reliable load switching.
