Intended Use

The PROFIBUS Power Hub Segment Coupler, as part of the Power Hub
System, serves as a Segment Coupler for connecting PROFIBUS PA
segments to PROFIBUS DP. Various Power Hub Power Supply soluti-
ons offer either simplex or redundant power to PROFIBUS PA seg-
ments. Power Hub Supplies for High-Power Trunk and the Fieldbus in-
trinsically safe concept DART are available.
The Segment Coupler ensures communication and galvanic isolation
between PROFIBUS PA and PROFIBUS DP. The Segment Coupler can
be used in all system environments in compliance with industry stan-
dard PROFIBUS DP Masters.
PROFIBUS PA is an extended version of the PROFIBUS DP that allows
for the physical transmission specifications of IEC 61158-2. Fieldbus
devices receive their electrical supply through the transmission li-
nes.The combination of PROFIBUS Power Hub components makes it
possible to connect and supply four PROFIBUS PA segments per Gate-
way to the PROFIBUS DP.
The Segment Coupler may be installed in Zone 2 Category 3G hazar-
dous areas. Types of protection are Ex nA (non-arcing) for Zone 2 Gas
Groups IIC, IIB, IIA.
The devices are only approved for appropriate and intended use. Igno-
ring these instructions will void any warranty and absolve the manufac-
turer from any liability.
The device must only be operated in the ambient temperature range
and at the relative humidity (non-condensing) specified.
