Ordering data
The PROFIBUS-PA
is an open field-bus standard
(EN 50 170, IEC 1158-2, DIN 19 245).
It was specifically developed for the re-
quirements of the Process Industry techno-
logy, in particular remote supply and
intrinsic safety. PROFIBUS-PA permits
several PA sensors and actuators to be
operated on one common bus. The devices
are supplied with power via 2-wire techno-
logy with the process data communication
being executed digitally.
Integration into the PROFIBUS-DP net-
work is carried out by means of a
Segment Coupler. Specific advantages of
PROFIBUS-PA :
• Reduced wiring costs
• Minimised design costs of the
process control system
• Remote interrogation and programming
of field devices
• Intrinsically safe version for applications
in potentially explosive atmospheres.
• Continuing development and support
through the PROFIBUS User and Trade
Organisation (PNO)

Weidmüller offers here the PROFIBUS-PA FB-Connector. In the event of service or plant modification,
the PROFIBUS-PA FB-Connector from Weidmüller permits the connection or replacement of field devices without interrupting the bus
system. Extensive accessories as well as preassembled cables and plugs round off the program.
