BPG400-SD requires an additional, separate power supply for the
DeviceNet interface (

Supply voltage at the DeviceNet con-
nector, (Pin 2 and Pin 3)
+24 VDC (+11 … 25 VDC)
Power consumption <2 W
The gauge is protected against reversed polarity of the supply voltage.
For reasons of compatibility, the expression "sensor cable" is used for all
BPG400 versions in this document, although the pressure reading of the
gauges with fieldbus interface (BPG400-SD, BPG400-SD and
BPG400-SR) is normally transmitted via the corresponding bus.
