Product Overview
The Foxboro FBM216 P0922VV I/A Series HART Communication Redundant Input Interface Module is a field I/O interface for HART-capable process instrumentation used in Foxboro I/A Series control systems. It brings smart field-device information into the control architecture while supporting a redundant input arrangement for applications where continuity of measurement is an important part of the system design.
In a typical process plant, smart transmitters provide continuous measurements such as pressure, flow, temperature, or level. In addition to the primary measurement, HART communication can carry device identification, configuration information, status, and diagnostic data. The FBM216 provides the interface between these field instruments and the I/A Series control-system environment.
The module is suited to process applications where field instrumentation, HART communication, and input redundancy need to work together. During commissioning or troubleshooting, the complete signal path should be considered, including the transmitter, field wiring, termination, input interface, and control-system configuration.

Working Principle
The FBM216 provides the interface between HART-capable field instruments and the Foxboro I/A Series control system. The module handles the field I/O interface while the actual measurement originates at the connected process instrument.
1. Process measurement
A smart transmitter measures a process variable such as pressure, flow, temperature, or level and produces the corresponding field signal.
2. Redundant input arrangement
Where redundancy is required by the application, the associated input paths are arranged according to the system design. The FBM216 provides the interface through which the configured field inputs enter the I/O architecture.
3. HART communication
HART adds a digital communication layer to the field instrument connection. Depending on the transmitter, information such as device identification, configuration, status, and diagnostics can be exchanged.
4. I/O interface
The FBM216 receives the field information and interfaces it with the I/A Series system. It does not perform the physical process measurement; instead, it provides the connection between field instrumentation and system-level processing.
5. Control-system processing
The acquired process value can be used for monitoring, alarming, calculations, sequencing, or closed-loop control. HART information can separately support instrument configuration and maintenance.
Role in a Foxboro I/A Series Redundant HART Control Architecture
The FBM216 occupies the field I/O layer between smart instrumentation and the I/A Series control system. Its redundant input capability becomes part of the wider architecture that includes field devices, wiring, I/O configuration, and control logic.

Installation and Maintenance
- Verify the system assignment — Confirm that the FBM216 corresponds to the intended I/O position and approved system documentation.
- Check field-device compatibility — Verify that connected instrumentation supports the intended HART and input arrangement.
- Review wiring documentation — Check instrument tags, input assignments, terminal references, and redundant signal paths.
- Apply electrical isolation — Follow approved plant isolation procedures before working on field circuits.
- Verify transmitter configuration — Confirm the connected smart instruments are configured for the intended application.
- Inspect field wiring — Check conductors and termination points for loose connections, damage, corrosion, or other visible problems.
- Check each input path — Verify the expected signal path for the configured redundant arrangement.
- Verify HART communication — If digital device information is unavailable, inspect the transmitter, wiring, I/O interface, and system configuration.
- Check I/O configuration — Confirm that the control-system configuration matches the intended FBM216 installation.
- Compare measurements — Where applicable, compare redundant or independent measurements to identify discrepancies.
- Review diagnostics — Use available HART and system diagnostic information to investigate instrument or communication problems.
- Document changes — Record approved changes to instruments, wiring, I/O assignments, and redundancy configuration.

Technical FAQs
What is the purpose of the Foxboro FBM216 P0922VV?
The FBM216 P0922VV provides a HART communication redundant input interface for smart field instrumentation within a Foxboro I/A Series control system. It connects field measurement and HART communication with the system’s I/O architecture.
What does the redundant input function mean in this application?
It refers to the input arrangement used to support the required level of input continuity within the overall control-system design. The actual redundancy strategy depends on the associated field devices, wiring, I/O configuration, and control architecture.
What information can be obtained through the HART communication layer?
Depending on the connected field instrument, HART communication can provide device identification, configuration information, status, and diagnostic data in addition to the primary process measurement.
What should be checked if one input path does not agree with another?
Check the associated field instruments first, then inspect the corresponding wiring, termination points, input assignments, and FBM216 configuration. Comparing the measurements and available HART diagnostic information can help determine whether the discrepancy originates from the instrument, wiring, I/O interface, or configuration.
