(output voltage U
O
of the segment (depending on segment coupler used)
coupler) see PA specification, e.g.
- non-Ex 22 V DC (nominal voltage of the segment
coupler) max. 32 sensors on one two-wire
cable
- Ex 13.5 V DC (nominal voltage of the segment
coupler) max. 10 sensors on one two-wire
cable (typically 8 sensors)
Current consumption constantly 10 mA (no leakage current output)
Load depending on segment coupler, see
technical data of the segment couplers and
Profibus specification
Measuring range
VEGAFLEX 54 rod 0.15 ... 4 m (with DK value > 4: 0.1 … 4 m)
cable 0.15 … 20 m
(with DK value < 4: 0.3 … 20 m)
Output signal
digital (Profibus) Two-wire technology:
The digital output signal (measuring signal) is
modulated onto the power supply and further
processed in the PLC or process control room .
Integration time 0 … 999 seconds (adjustable)
Adjustment
- adjustment software VEGA Visual Operating on Master-Class 2 PC
- adjustment module MINICOM in the sensor or in the external instrument (optional)
- process adjustment interface PACTware
TM (under which VVO runs as a subprogram)
- SIMATIC PDM in conjunction with Electronic Device Description (EDD)
