■
Overview
•
Bus cable for fieldbus systems according to IEC 61158-2,
e.g. PROFIBUS PA
•
High interference immunity thanks to double shielding
•
Different variants for different applications (hazardous areas,
non-hazardous areas)
•
Easy length measurement thanks to printed meter markings
■
Benefits
•
Length can easily be determined due to meter length
markings printed on the cable
•
Complete range of cables for hazardous and non-hazardous
areas
•
Reduction of types and parts thanks to a uniform connection
system for PROFIBUS PA
■
Application
For the construction of fieldbus networks according to IEC
61158-2 (for example PROFIBUS PA), different color-coded ca-
ble types are available for the different types of applications
(hazardous, non-hazardous areas).
UL approvals
Different cable variants are offered with appropriate UL approv-
als for laying in cable bundles and cable racks according to the
specifications of NEC (National Electrical Code) Article 800/725.
■
Design
•
Shielded, twisted-pair cable with circular cross-section
•
System-wide grounding concept can be implemented using
the external shield of the bus cable and the grounding
terminals of the SpliTConnect system.
•
Printed meter marks.
Cable types
•
FC Process Cable:
Special bus cable compliant with IEC 61158-2 for use in
hazardous (Ex) and non-hazardous (non-Ex) areas.
•
Bus segments with RS485 and IEC 61158-2 transmission
procedures are linked by means of the segment coupler/link.
