Wiring digital inputs / digital outputs
Digital inputs
The 4 switching digital inputs activate one of the 16 field sets in a binary combination
as an evaluation case.
The digital inputs are decoupled from the supply voltage of the device. They have a
common reference point (IN
GND
), meaning they are not decoupled from one another.
The structure and wiring principle of the digital inputs are shown below.
