Note
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.
CAUTION
The common-mode range must not be violated.
The analog differential voltage signals can have a maximum offset voltage of +/-30 V with
respect to the ground potential. If the range is violated, incorrect results may occur during
analog/digital conversion.
