Max. connectable cross-section: 0.5 mm
Type: Spring-loaded terminal 1 (see Appendix A)
1) AI: analog input, AO: analog output
Note
An open input is interpreted as approximately "0V".
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 (see Electrical connection).
Caution
The common-mode range must not be infringed.
The analog differential voltage signals can have a maximum offset voltage of +/-30 V with
respect to the ground potential. If the range is infringed, incorrect results may occur during
analog/digital conversion.
