6/12-Spur, Open-Frame, Fieldbus Barrier
Brand: MTL InstrumentsThe 9387-FB2: 6-spur and 9388-FB2: 12-spur Fieldbus Barrier assemblies provide intrinsically safe spur connections from a high-energy trunk, for connection to suitably certified Foundation™ fieldbus H1 instruments.
Each unit comprises pre-wired and assembled system components on a stainless steel baseplate, for installation into a suitably certified field enclosure.
Connection facilities are provided for the trunk and spur wiring, as well as all electronic modules needed to support a fully-working Fieldbus Barrier. In a typical application, an Ex e: increased safety certified field enclosure will be selected to allow installation in a Zone 1 hazardous area; third-party approval of the enclosure and contents is normally required.
Alternative uses include applications that are not satisfied by the 9370-FB2 range of Fieldbus Barriers in standard enclosures, such as the installation of multiple fieldbus segments inside a single field enclosure.
