Overview

The F2D0‑FB‑EX4.CG Safety Barrier is a compact, stand‑alone FieldBarrier module engineered for installation in Zone 1/Division 2 hazardous areas. It connects up to four intrinsically safe field devices located in Zone 0/Division 1, ensuring safe signal transmission and power distribution. Moreover, each output channel includes short‑circuit current limitation, preventing a single fault from affecting the entire segment. In addition, integrated Power, Communication, and Error LEDs provide clear diagnostics, simplifying maintenance and troubleshooting.

This barrier supports both FISCO and Entity models, making it highly versatile for different intrinsic safety concepts. Therefore, it is widely adopted in oil, gas, chemical, and pharmaceutical industries where reliable fieldbus communication and intrinsic safety are mandatory.

Technical Data

Typical Applications

• Hazardous area instrumentation loops requiring intrinsically safe fieldbus connections

• Process automation systems in chemical plants and refineries

• Oil and gas platforms where multiple field devices must be safely connected

• Pharmaceutical manufacturing needing reliable diagnostics and safe communication

• Distributed control systems (DCS) integrating FOUNDATION Fieldbus or PROFIBUS PA networks

For instance, offshore operators deploy the F2D0‑FB‑EX4.CG to connect multiple transmitters and valve positioners in Zone 0, while chemical plants rely on its short‑circuit protection to maintain continuous operation even if one device fails.
