NOTICE!
Risk of faulty measurements!
The negative pole/ground potential at the sensors must not have too large a
potential difference with respect to ZP (max. ± 1 V within the full signal range).
Make sure that the potential difference never exceeds ± 1 V.
The following figure shows the connection of active-type analog sensors (voltage) to differential
analog inputs AI0 and AI1. Proceed with AI2 and AI3 in the same way.

For the measuring ranges that can be configured, please refer to the sections Measuring
Ranges

Chapter 1.7.2.2.10 “Measuring ranges” on page 650 and Parameterization

Chapter 1.7.2.2.7 “Parameterization” on page 640.
To avoid error messages, configure unused analog input channels as "unused".
Use of analog inputs as digital inputs
Several (or all) analog inputs can be configured as digital inputs. The inputs are not galvanically
isolated against the other analog channels.
The following figure shows the connection of digital sensors to the analog input AI0. Proceed
with the analog inputs AI1 to AI3 in the same way.
