• 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-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.
