Eaton MTL - 9377-FB-R FIELDBUS BARRIER MODULE, PLUGGABLE, 6 SPUR

9377-FB-R Intrinsically Safe Barrier

The 9377-FB-R Fieldbus Barrier module is the main active component in the 9370-FB range Fieldbus Barrier System for Foundation fieldbus networks and provides six intrinsically safe fieldbus spurs from a single incoming trunk.
The 9377-FB-R Fieldbus Barrier module may be fitted or removed without the need to isolate trunk power. The trunk connections to the barrier module on the carrier have spark suppression by design and cannot cause ignition while they are being connected or disconnected. Capable of supporting heavily loaded fieldbus segments and long trunk cable lengths the 9377-FB-R barrier can be installed in Zone 1 (gas) or Zone 21 (dust) hazardous areas with spurs connected into Zone 0

Unlike conventional Fieldbus Barrier products that are based on stand-alone modules, this intrinsically safe barrier is supplied as a complete, factory-assembled enclosure system in stainless steel that doesn’t require additional wiring, customised housings or complex ancillary components. Integrating the electrical and mechanical components the 9377-FB-R provides a complete, ergonomic solution for High Energy Trunk applications in hazardous areas combined with an 40% smaller enclosure footprint than existing implementations.
The 9377-FB-R module may be used as a direct replacement for type 9377-FB in all 937x-FB-xx-xx range (enclosure) and 938x-FB-xx range (open frame) Fieldbus Barrier systems.
