Product Description

The FBM215 (P0922VT) is an 8-channel HART-enabled analog output module for the Foxboro I/A Series DCS. It delivers 4–20 mA DC control signals while simultaneously supporting bidirectional HART digital communication with smart field devices such as valve positioners and actuators. This dual-layer communication enables advanced diagnostics, configuration, and calibration without interrupting the primary control signal.

Designed for harsh industrial environments, the FBM215 incorporates per-channel galvanic isolation to protect the system fieldbus from electrical noise, ground loops, and field-side transients. The module integrates seamlessly with the Foxboro redundant Fieldbus architecture, ensuring high availability and reliable operation.

Technical Specifications

Typical Applications

• Smart valve positioner control in high-pressure steam systems

• Chemical dosing and injection pump modulation

• Damper and actuator control in environmental systems

• Asset management and diagnostics using HART data (valve travel, cycle counts)

Frequently Asked Questions

Does the FBM215 (P0922VT) support FDT/DTM technology?
Yes. When used within a Foxboro I/A Series or EcoStruxure™ Foxboro DCS, the FBM215 transparently passes HART data, enabling full FDT/DTM-based asset management and access to complete device parameter sets.

What happens if HART communication fails?
The 4–20 mA analog loop operates independently of the HART digital signal. If digital communication is lost, the FBM215 continues to deliver the analog control output, maintaining process stability while reporting the communication fault.
