⚙ How It Works
Each relay allows you to control AC or DC loads safely from a microcontroller:
-
When the relay is energized, the indicator LED lights up.
-
When the relay is off, the indicator turns off.
-
The pull-down circuit prevents unwanted triggering during startup.
-
The transistor drive ensures stable switching and protects the controller.
