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 also be operated as:
- Pulse or status output
- Only Prowirl 73: as a PFM output (pulse/frequency modulation) together with an RMC or RMS 621 flow computer
C Ground terminal (relevant for remote version)
D Only Prowirl 72: PFM (pulse-frequency modulation) wiring
