Electrical connection Prowirl 73
a - HART: Power supply, current output
- PROFIBUS PA: 1 = PA+, 2 = PA–
- FOUNDATION Fieldbus: 1 = FF+, 2 = FF–
b Optional frequency output (not for PROFIBUS PA and FOUNDATION Fieldbus), can als be operated:
- as pulse or status output (except PROFIBUS PA and FOUNDATION Fieldbus)
- together with the flow computer RMC or RMS 621 as PFM output (pulse-frequency modulation)
c Ground terminal (relevant for remote version)
Connecting the
remote version
Note!
The remote version must be grounded. In doing so, the sensor and transmitter must be connected to the same
potential matching.

Supply voltage Non-Ex: 12...36 V DC (with HART 18...36 V DC)
Ex i: 12...30 V DC (with HART 18...30 V DC)
Ex d: 15...36 V DC (with HART 21...36 V DC)
PROFIBUS PA and FOUNDATION Fieldbus
Non-Ex, Ex d: 9...32 V DC
Ex i: 9...24 V DC
Current consumption → PROFIBUS PA: 16 mA, FOUNDATION Fieldbus: 16 mA
