Thermocouple Interface Module New | Foxboro RH926EQ FBM202

Product Overview

The Foxboro FBM202 (Part Number: P0962EQ) serves as a high-precision 8-channel analog input interface for the Foxboro I/A Series and Evo™ distributed control systems. This module specializes in the acquisition of low-level millivolt (mV) signals and standard thermocouple inputs (Types J, K, T, E, N, S, R, B). It provides critical temperature data to the DCS for furnace control, boiler monitoring, and turbine exhaust analysis. We supply this unit as 100% Brand New and Original, ensuring your facility receives factory-calibrated accuracy and the highest level of signal stability.

Technical Specifications

Engineering Advantages

• Precision Cold Junction Compensation: The FBM202 includes a dedicated, isolated RTD channel specifically for Reference Junction Compensation (CJC). This integrated hardware compensates for ambient temperature variations at the termination point, providing highly accurate absolute temperature readings without requiring external compensation devices.

• Advanced Burnout Detection: The module monitors thermocouple integrity in real-time. If a sensor wire breaks or fails, the FBM202 immediately triggers a burnout detection signal (upscale indication), allowing the control system to switch to a fail-safe mode and prevent process overheating.

• Superior 1500V Isolation: Every channel features full galvanic isolation rated up to 1500 V DC. This robust protection eliminates ground loop errors and prevents high-voltage transients from propagating from the field sensors to the control processors, which is vital in power plant and smelting environments.

• High-Resolution Signal Conversion: Utilizing 16-bit Sigma-Delta ADCs, the module delivers exceptional resolution for minute voltage changes. It filters out industrial noise and electromagnetic interference (EMI) through configurable integration times, ensuring stable data in electrically "noisy" areas near large motors or switchgear.

• Rugged ISA Class G3 Coating: To withstand corrosive industrial gases like Hydrogen Sulfide and Chlorine, the FBM202 carries an ISA Class G3 rating. This protective conformal coating ensures the module remains functional in non-climate-controlled cabinets or offshore platforms.

FAQs

Which part numbers does the P0962EQ replace?

The P0962EQ is the current high-performance version that supersedes and replaces older variants, including the P0926EQ and RH926EQ. It maintains full backward compatibility with existing I/A Series 200 baseplates.

How does the module handle sensor failure?

The FBM202 features built-in burnout detection. When it detects an open circuit in the thermocouple wiring, it automatically drives the signal upscale, alerting the operator and the DCS logic to a sensor fault.

Does the module support different thermocouple types simultaneously?

Yes. You can configure each of the 8 channels independently for different thermocouple types (e.g., Type K on channel 1 and Type J on channel 2) or standard millivolt inputs through the system software.

Is this a new original unit or a "used" GPP unit?

While some markets trade in "Used GPP" (General Purpose Process) stock, we explicitly offer this unit as 100% Brand New and Original. It ships in original factory packaging, meeting all current Schneider-Foxboro industrial certifications and safety standards.
