Eaton F300-A01-5 Trunk-spur partition -pack of 5

The 937x-FB2-Px-SS range of Fieldbus Barriers are field

mounted 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-Px range is

supplied as complete, factory-assembled systems in stainless

steel (SS) enclosures that do not require additional wiring,

customised housing or complex ancillary components.

Electrical and mechanical aspects of the design are integrated

for a ergonomic solution for ‘High Energy Trunk’ applications

in hazardous areas.

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.
