Application Scenarios
At a North Sea offshore platform, frequent Fieldbus communication dropouts in a separator train were causing spurious shutdowns. Investigation revealed voltage sag due to an undersized, non-redundant power supply. Engineers replaced the legacy unit with dual-redundant FOXBORO F8627X modules configured in parallel. The new setup delivered stable 32 V DC at 300 mA with real-time current monitoring via the I/A Series operator station. Over the next 18 months, Fieldbus segment availability rose from 92% to 99.99%, and maintenance calls for “ghost alarms” dropped by 90%. In this high-risk environment, the F8627X became the silent guardian of digital field communication integrity.

Technical Principles and Innovative Values
Innovation Point 1: Dual Function as Power Supply + IS Barrier
The F8627X eliminates the need for separate isolators by integrating intrinsic safety barrier functionality directly into the power conditioner—reducing cabinet space, wiring complexity, and cost.
Innovation Point 2: High Current Capacity for Dense Device Segments
With 350 mA output, the F8627X supports more devices per segment than many competitors (typically limited to 250–300 mA), lowering infrastructure costs in large plants.
Innovation Point 3: Seamless I/A Series Integration with Central Diagnostics
When used with FOXBORO’s Fieldbus Interface Module (F8601A), the F8627X’s health status appears in the I/A Series workstation—enabling predictive maintenance before communication fails.
Innovation Point 4: Robust Noise Immunity for Electrically Harsh Plants
Designed for refineries and chemical plants, the F8627X includes advanced filtering to suppress EMI from VFDs, motors, and switchgear—ensuring signal integrity over long trunk cables.
Application Cases and Industry Value
In a U.S. ethylene plant, a reactor temperature control loop using FF smart transmitters suffered intermittent data loss during compressor startups. The FOXBORO F8627X’s superior noise rejection and stable voltage regulation resolved the issue without rewiring—saving an estimated $ 250K in downtime and engineering costs.
Another example: a Middle Eastern LNG facility standardized on F8627X across all 42 Fieldbus segments due to its long-term availability commitment from Schneider Electric. Even 10+ years after initial installation, spare units remain accessible—critical for brownfield site sustainability.
