For FOUNDATION™ fieldbus networks in
hazardous areas
Complete enclosure system for 6 or 12
intrinsically safe spur connections
Mount in Zone 1 (gas) or 21 (dust)
with spurs connected into Zone 0
Compatible with FISCO and Entity certified
fieldbus instruments
Compact, modular construction
Ergonomic mechanical design
Pluggable system components,
without ‘gas free’ constraints
Optional, integrated surge protection
for trunk and spurs
The 937x-FB2-Px-PP range of Fieldbus Barriers are fieldmounted wiring hubs that create up to twelve intrinsically safe
spur connections from a high-energy trunk, for connection
to suitably certified FOUNDATION™ fieldbus H1 instruments.
Capable of supporting heavily loaded fieldbus segments
and long trunk cable lengths, the Fieldbus Barriers may be
installed in Zone 1 (gas) or Zone 21 (dust) hazardous areas,
with the trunk wiring implemented using suitably protected
cable and increased safety (Ex e) connection facilities.
Each intrinsically safe spur is capable of supporting a FISCO
or ‘Entity’ certified fieldbus device located in a Zone 0 or
1 hazardous area. The short-circuit protected spurs are
galvanically isolated from the trunk and require no protective
ground connection in the field.
Unlike conventional Fieldbus Barrier products that are
based on stand-alone modules, the 937x-FB2-PC-PP range
are supplied as a complete, factory-assembled systems in a
glass reinforced plastic (GRP) enclosures that does not require
additional wiring, customised housing or complex ancillary
components. Electrical and mechanical aspects of the design
are integrated, providing the industry’s first complete,
ergonomic solution for ‘High Energy Trunk’ applications in
hazardous areas.
(9373-FB2-PS-PP version shown)
The key modular components of the system (Fieldbus
Barriers and Surge Protectors) may be ‘hot-plugged’ by
design and without gas-clearance procedures or separate
isolating switches. This virtually eliminates the risk
associated with hazardous area maintenance activities,
speeds module replacement and avoids the need for
specialist operator training.
Optional features include pluggable surge protection
components for the fieldbus trunk and individual spurs.
Connection facilities with generous room for cable
management are provided within the Fieldbus Barrier
enclosure for the trunk and spur wiring. Where appropriate,
the trunk wiring may be extended from one Fieldbus Barrier
enclosure to another.
Enclosure systems for 6 or 12 spurs are supported. For
added flexibility, the 12-spur enclosure can be specified partpopulated with one 6-spur barrier module installed (model no.
9374-FB2-PC-PP-001). This permits future expansion from six
to twelve spurs simply by plugging in an additional module.
The 937x-FB2-PC-PP range of Fieldbus Barriers are buspowered and requires no additional power supply in the field.
When used with a fieldbus host control system, power for the
trunk may be provided by MTL F800 or 9180 range of fieldbus
power supplies in redundant or non-redundant format.
