voltage measurement 0...32 V (IN_VOLTAGE_32)
ratiometric voltage measurement / operating voltage ratio (IN_VOLTAGE_RATIO)
The potentiometer forms a voltage divider to also simulate analogue values. When a value is set on a
potentiometer and the corresponding switch is activated, this value is sent to the controller.
In case of binary use of the input, the potentiometer has to be positioned at the right end stop. That
means that the switch supplies the operating voltage (+24 V DC), i.e. an H signal, to the input.
Since we work under ideal conditions (short cable lengths, "clean" voltage supply, no internal and
external noise signals), ground can be connected via GNDsys in the analogue modes.
► If used in the field, the notes on laying and connecting the signal, voltage and ground
cables in the original operating instructions have to be observed.

The output circuit is shown in the image below using [OUT0000] as example.
The following modes can be simulated on the outputs:
binary output (OUT_DIGITAL_CSO)
PWM output

Should a connection to the controller not be possible, the interface parameters can be reset to factory
setting using the switch [RESET COM].
