The 937x-FB2 Fieldbus Barrier range are field-mounted wiring hubs that create 6 or 12 intrinsically safe spur connections from a high-energy trunk, for connection to suitably certified Foundation™ fieldbus H1 instruments. They are capable of supporting heavily loaded fieldbus segments and long trunk cable lengths, and can be installed in Zone 1 (gas) or Zone 21 (dust) hazardous areas. The redundant fieldbus barrier will tolerate hardware failures without interrupting the operation of the fieldbus segment for those applications requiring the highest level of availability.
