Foxboro FBM216B P0927AJ 8-Port Analog Input Module Original

Product Overview

The Foxboro FBM216B (Part Number: P0927AJ) functions as a high-density, 8-channel analog input interface specifically engineered for Foxboro I/A Series and Evo™ (EcoStruxure Foxboro DCS) platforms. This module acquires standard 4–20 mA DC signals while simultaneously managing bidirectional HART® digital communication via Frequency Shift Keying (FSK). By providing a dedicated HART modem for every channel, the FBM216B enables continuous access to secondary variables and field device diagnostics without impacting the primary control loop. We supply this unit as 100% Brand New and Original, ensuring peak performance for your critical process automation infrastructure.

Technical Specifications

Engineering Advantages

• Dedicated HART Modem Architecture: The FBM216B integrates a dedicated HART modem into each of its 8 channels. This allows for parallel digital communication across all ports, ensuring that the DCS retrieves device parameters and diagnostic data at the highest possible speed without serial multiplexing delays.

• Superior Galvanic Isolation: Every channel features full galvanic isolation rated at 600 V AC. This architecture eliminates ground loop currents and prevents high-voltage transients from migrating across channels or damaging the internal system Fieldbus, which is critical for maintaining signal integrity in power plants and chemical refineries.

• Fault-Tolerant Redundancy: The module supports paired redundant configurations (Master/Tracker mode). In the event of a module failure, the tracker unit immediately assumes control via the redundant Fieldbus, providing zero-bump transfers for high-availability process safety and control loops.

• High-Resolution Signal Acquisition: Utilizing 15-bit Sigma-Delta conversion technology, the FBM216B delivers high-accuracy measurements with excellent noise rejection. A Common Mode Rejection ratio of >100 dB ensures that 50/60 Hz industrial noise does not corrupt the process variables.

• Ruggedized for Extreme Environments: The module carries an ISA Class G3 rating, protecting sensitive internal electronics against corrosive gases (such as H2S and Chlorine) and high humidity. Its wide operating temperature range (–20°C to +70°C) permits installation in non-conditioned industrial cabinets.

FAQs

Does the FBM216B support the latest HART 7 devices?

Yes. The FBM216B P0927AJ fully supports HART versions 5, 6, and 7. It communicates with intelligent field devices using universal, common practice, and device-specific command sets to retrieve advanced diagnostics and configuration data.

How does this module handle loop power for transmitters?

The FBM216B provides a loop supply of ≥18.5 V DC at 20.5 mA per channel. This satisfies the power requirements for standard 2-wire 4–20 mA transmitters directly from the module, simplifying field wiring.

Can I replace an FBM216B while the system is running?

Yes. The FBM216B is hot-swappable when used with compatible Foxboro baseplates. This allows maintenance teams to replace the module without disconnecting field wiring or interrupting power to other modules in the same rack.

Is this a new original unit or a refurbished one?

We guarantee that every Foxboro FBM216B we provide is 100% brand new and original factory stock. Each unit arrives in original packaging, meeting all factory-specified tolerances for accuracy and reliability.
