MTL Instruments, a unit of Cooper Crouse-Hinds, launched a range of Fieldbus Barrier wiring hubs called the 9370-FB Series. These hubs are to connect safe field instruments to Foundation fieldbus networks in hazardous areas. The Fieldbus Barrier “retains the major benefits of the “High Energy Trunk” technique whilst removing the drawbacks associated with existing Field Barrier implementations,” says the release. The 9370-FB Series contain a fixed carrier assembly and pluggable components that come in stainless steel or carbon-loaded GRP. While the equipment is live, all parts of the system containing electronic circuits are housed in “pluggable” modules that can be removed and replaced. The system’s barrier modules, terminator and optional surge protection devices are all certified for removal and replacement in hazardous areas, according to MTL.
