MTL Open-Frame Simplex Fieldbus Barrier Assembly

2025-03-12

The MTL open-frame simplex fieldbus barrier assembly provides 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 such as the installation of multiple fieldbus segments inside a single field enclosure.
