• For Foundation™ fieldbus networks in hazardous areas

• Redundant configuration for super high system availability

• Complete enclosure systems for up to 6 intrinsically safe spur connections

• Failure alarm direct to host control system via integrated fieldbus device

• Mount in Zone 1 (gas) or 21 (dust) with spurs connected into Zone 0

• Compatible with FISCO and Entity certified fieldbus instruments

• Ergonomic mechanical design

•  Pluggable system components, without ‘gas free’ constraints

• Optional, integrated surge protection for trunk and spurs

The 9372-FB Redundant Fieldbus Barriers are field-mounted wiring hubs that create

up to six intrinsically safe spur connections from a high-energy trunk, for connection to

suitably certified Foundation™ fieldbus H1 instruments. They 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.
