Intrinsically Safe Fieldbus Barriers
MTL’s new 9370-FB Series Fieldbus Barrier establishes a new benchmark for fieldbus networks in hazardous areas. It retains the major benefits of the High Energy Trunk technique while removing the drawbacks associated with existing Fieldbus Barrier implementations. The result is lower cost, safer operation and higher reliability throughout the life-cycle of the fieldbus network, with benefits not only for the plant operator but also for all parties involved in the design and installation process.
- Live-working in hazardous areas
- Supports 6- and 12- spur applications with standard enclosures
- Integrated trunk and spur surge protection as initial build or retro fit
- Mount in Zone 1 or Zone 2
- Compatible with Entity and FISCO certified IS field devices
- Available in GRP or stainless steel enclosures

The 9378-FT Fieldbus Terminator provides 'far end' termination of the trunk cable for the the 9370-FB fieldbus Barrier when used in fieldbus networks. Specially certified connectors allow the 9378-FT to be removed and replaced while powered in a Zone 1 hazardous area.
The 9376-SP Trunk Surge Protector prevents surges and transient over-voltages induced on the trunk of the fieldbus network from damaging the system's internal components such as the Fieldbus Barrier Module and terminator. Like the 9378-FT, it can also be removed and replaced while powered in a Zone 1 hazardous area.
For maximum protection, the FS32 Surge Protection Device prevents surges and transient over-voltages conducted along the Spurs of fieldbus systems from damaging the the fieldbus barrier module.
