So if you activate the connected device, the voltage turns on the input and the signal is evaluated as logic HIGH(1). If the device is deactivated (turned off), the state is evaulated as a logic LOW(0). Using this, you can read for example S0 impulses from energy meters (water meter, electricity meter, ...) or buttons, movement (PIR) sensors or magnetic contacts and many others.
