Foxboro FBM207C (P0917GY) – 8-Channel Analog Output Module | I/A Series DCS Platform
Engineering Background
The Foxboro I/A Series Distributed Control System (DCS) has been a cornerstone of process automation in refining, petrochemical, power generation, and specialty chemical industries for decades. The FBM (Fieldbus Module) family forms the critical I/O backbone of this architecture, providing deterministic, high-integrity signal conditioning between field instrumentation and the control processor.
Product Positioning
The FBM207C (Foxboro part number P0917GY) is an 8-channel analog output module engineered for precision current-loop signal delivery to final control elements — including control valves, variable-speed drives, and positioners. It is designed for direct integration into I/A Series FBM enclosures and communicates natively over the Nodebus/Fieldbus backplane without additional gateways or converters.

- Long-Term Availability: Verified surplus stock sourced from decommissioned systems — fully tested prior to shipment
System Architecture & Signal Flow
The FBM207C resides in the FBM enclosure and communicates with the I/A Series Control Processor (CP) via the Nodebus backplane. The CP downloads setpoint values to the module, which performs D/A conversion and drives the 4–20 mA output to field wiring terminations on the associated FBM termination assembly (FTA). Field wiring connects from the FTA to the final control element (e.g., I/P transducer, valve positioner, or VFD analog input).
Signal path: CP → Nodebus → FBM207C → FTA → Field Device

Technical FAQ
Q: Is the FBM207C compatible with I/A Series Series 200 and Series 300 enclosures?
A: Yes. The FBM207C is compatible with standard I/A Series FBM enclosures used across Series 200 and Series 300 control system generations.
Q: Can the FBM207C be used with FOUNDATION Fieldbus or HART field devices?
A: No. The FBM207C outputs a conventional 4–20 mA analog signal. For HART or FF devices, Foxboro offers dedicated FBM modules (e.g., FBM214 for HART AO).
Q: What FTA (Field Termination Assembly) is required?
A: The FBM207C pairs with the Foxboro FBM207C-compatible FTA. Please confirm your enclosure model when ordering to ensure correct FTA compatibility.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all surplus modules. Extended warranty options available — contact us for details.
Q: Can I request a datasheet or wiring diagram?
A: Yes. Contact [email protected] and reference part number P0917GY. We will provide the relevant Foxboro technical documentation.
