Remarks
The sensor supply module always has 5
selectable voltage settings.
default selection: +5 V to +24 V
set jointly for all eight channels
optional, special order: +12 V or +15 V can
be replaced by +2.5 V
preferred selection with 2.5 V:
+2.5 V, +5.0 V, +10 V, +12 V, +24 V
optional, special order: +15 V can be
±
replaced by 15 V. This eliminates the
internal current- and quarter bridge
measurement.
