Operation
The relay is an electronic switch. When theIN pin is high / disconnected, COM is connected to NC (NC means normally closed).
When the IN pin is low, COM is connected to NO (NO means normally open).
Setting the “transistor” attribute to “pnp” inverts the logic: when IN is high, COM is connected to NO, and when IN is low / disconnected, COM is connected to NC.
