Cable specification
• A standard installation cable is sufficient if only the analogue signal is used. Use a screened cable when
working with a superimposed communications signal (HART).
Note!
Protective circuitry against reverse polarity, RFI and over-voltage peaks is built into the device (see also
Technical Information TI241F/00/en "EMC Test Procedures").
Note!
See TI402F/00/en for connection to Tank Side Monitor NRF590.
PROFIBUS PA
The digital communication signal is transmitted to the
bus via a 2-wire connection. The bus also provides the
auxiliary energy.
For further information on the network structure and
earthing and for further bus system components such
as bus cables, see the relevant documentation, e.g.
Operating Instructions BA034S "Guidelines for
planning and commissioning PROFIBUS DP/PA" and
the PNO Guideline.
Cable specification:
• Use a twisted, shielded two-wire cable, preferably
cable type A
Note!
For further information on the cable specifications, see Operating Instructions BA034S "Guidelines for planning
and commissioning PROFIBUS DP/PA", PNO Guideline 2.092 "PROFIBUS PA User and Installation Guideline"
and IEC 61158-2 (MBP).
