Note
Permissible voltage values
In order to avoid incorrect results of the analog-digital conversion, the analog differential
voltage signals can have a maximum offset voltage of +/-30 V with respect to ground
potential.
Note
Open input
An open input is interpreted as approximately "0 V".
The power supply of the analog inputs/outputs is drawn via the option slot of the Control Unit
and not via X424.
The shield is connected to the Control Unit.
