VEGAPULS 43 – Profibus PA 47
7 Technical data
7.1 Technical data
Power supply
Supply voltage 9 … 32 V DC
Supply voltage dependent on
output voltage U
O
of the
segment coupler (see PA
specification) e.g.
- non-Ex
22 V DC (max. 32 sensors on one
two-wire cable)
- E x 15 V DC (max. 10 sensors on one
two-wire cable)
Current consumption constantly 10 mA (no leakage current output)
Resistance of the signal cable dependent on segment coupler, see
technical data of the segment coupler and
Profibus specification
Unit and measuring range
Unit distance between product surface and
process fitting (e.g. lower flange side of the
sensor)
Measuring range
- DN 50, ANSI 2“ 0 … 10 m
- DN 80, 100, 150, ANSI 3“, 4“, 6“ 0 … 20 m
- Clamp 2“ 0 … 10 m
- Clamp 3“, 4“ 0 … 20 m
Output signal
Signal output digital output signal in two-wire technology
(PA): The digital output signal (meas. signal)
is superimposed on the power supply and
further processed in the PLC or processing
system max. 32 sensors on one two-wire cable
(Ex: max. 10)
Resistance/Load of the signal cable dependent on the segment coupler (see
technical data of the segment coupler) and
the existing bus cable (see Profibus-
cable parameters)
Integration time (adjustable) 0 … 999 seconds
Two-wire technology:
The digital output signal (meas. signal) is superimposed on the power supply and further
processed in the signal conditioning instrument or in the processing system. Up to 15
sensors can be operated on one two-wire cable (in Ex area up to 5 sensors).
Four-wire technology:
Separate power supply. The digital output signal (meas. signal) is transmitted in a cable
separate from the power supply.
