VEGA VEGAFLEX 52P (Profibus PA) - Manual (Page 14)

14 VEGAFLEX 51P and 52P
1) Similar to DIN 16 086, reference conditions according to IEC 770, e.g.
temperature 15°C … 35°C; moisture 45 % … 75 %; pressure 860 mbar … 1060 mbar
3) The adjustment time (also actuating time, response time or adjustment period) is the time the sensor
requires to output the correct level (with max. 10% deviation) after a quick level change.
1.7 Technical data
Power supply
Supply voltage 9 … 32 V DC)
(output voltage U
O
of the segment dependent on the segment coupler used
coupler) see PA specification, e.g.
- non Ex e.g. 22 V DC (nominal voltage of the segment
coupler) max. 32 sensors on one two-wire
cable
- E x 13.5 V DC nominal voltage of the segment
coupler max. 10 sensors on one two-wire
cable (typical 8 sensors)
Current consumption constant 10 mA (no leakage current output)
Cable load dependent on the segment coupler, see
technical data of the segment couplers and
Profibus specification
Measuring range
VEGAFLEX 51 0.3 … 10 m
VEGAFLEX 52 0.3 … 20 m
Output signal
digital (Profibus) two-wire technology:
the digital output signal (meas. signal is
modulated onto the power supply and is further
processed in the PLC or in the process control
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 indicating instrument
(optional)
- process adjustment interface PACTware TM (VVO as subprogram)
- SIMATIC PDM in conjunction with Electronic Device Description (EDD)
