MTL Open-Frame Redundant Fieldbus Barrier

2025-03-12

The MTL open-frame redundant fieldbus barrier provides intrinsically safe spur connections from a high-energy trunk, for connection to suitably certified Foundation fieldbus H1 instruments. The 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.
