DRAFT 09 January 2015 Technical data MTL fieldbus networks November 2016 EPS 937x-FB2-Px-PP Rev 3 937x-FB2-Px-PP range Fieldbus Barriers, 6 and 12 spur, Glass Reinforced Polyester (GRP) enclosures • • • • • • • • 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-PP range of Fieldbus Barriers are fieldmounted 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-PC-PP range are supplied as a complete, factory-assembled systems in a glass reinforced plastic (GRP) enclosures that does not require additional wiring, customised housing or complex ancillary components. Electrical and mechanical aspects of the design are integrated, providing the industry’s first complete, ergonomic solution for ‘High Energy Trunk’ applications in hazardous areas. (9373-FB2-PS-PP version shown) 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. Enclosure systems for 6 or 12 spurs are supported. For added flexibility, the 12-spur enclosure can be specified partpopulated with one 6-spur barrier module installed (model no. 9374-FB2-PC-PP-001). This permits future expansion from six to twelve spurs simply by plugging in an additional module. The 937x-FB2-PC-PP range of Fieldbus Barriers are buspowered and requires no additional power supply in the field. When used with a fieldbus host control system, power for the trunk may be provided by MTL F800 or 9180 range of fieldbus power supplies in redundant or non-redundant format.
