Foxboro FBM201 P0914SQ – 8-Channel Analog Input Module | DCS I/A Series Platform
Engineering Background
The Foxboro FBM201 (Part No. P0914SQ) is a field-proven analog input module designed for the Foxboro Distributed Control System (DCS) I/A Series platform — one of the most widely deployed process control architectures in refining, petrochemical, power generation, and specialty chemical industries. The FBM201 serves as the primary interface between field instrumentation and the I/A Series control network, converting analog process signals into digital data for real-time process monitoring and closed-loop control.
Product Positioning
Engineered for mission-critical continuous process environments, the FBM201 P0914SQ is the preferred replacement and spare module for facilities running Foxboro I/A Series DCS infrastructure. Its compatibility with existing I/A Series fieldbus wiring, termination assemblies, and control software makes it the lowest-risk, highest-reliability upgrade path for aging analog input subsystems.

System Architecture & Signal Flow
The FBM201 P0914SQ mounts directly onto an I/A Series FBM baseplate, which provides both power and Nodebus communication connectivity. Field wiring terminates at the associated termination assembly (TA), which connects to the FBM201 via a standard 50-pin ribbon cable. Analog signals from field transmitters (4–20 mA or 1–5 V) are multiplexed, filtered, and converted by the on-board 16-bit ADC. Digitized process values are transmitted over the FBM Bus to the I/A Series Control Processor (CP), where they are available to control strategies, historian, and operator displays within the I/A Series software environment (IACC / FoxView / AIM*AT).

Technical FAQ
Q: Is the FBM201 P0914SQ compatible with Foxboro Evo DCS?
A: The FBM201 is designed for the classic I/A Series platform. Compatibility with Foxboro Evo depends on the specific Evo configuration and CP version — contact us for a compatibility assessment.
Q: Can this module be used in SIL 2 safety loops?
A: The FBM201 is not a SIL-certified safety module. For SIL 2/3 applications, Foxboro FBM228 or dedicated safety-rated I/O should be specified.
Q: What termination assembly is required?
A: The FBM201 P0914SQ is typically paired with the P0916AA or P0916AB termination assembly. Confirm your existing TA model before ordering.
Q: Do you provide a test report or functional verification certificate?
A: Yes. A functional test record is available upon request for orders of 2+ units.
Q: What is the lead time for stock items?
A: In-stock units ship within 1–3 business days. Lead time for sourced units is typically 2–4 weeks.
