FBM202 P0916AC | Foxboro | I/A Series Thermocouple/mV Input Module

Product Overview

The Foxboro FBM202 (P0916AC) serves as a high-precision interface for temperature monitoring within the Foxboro I/A Series and Foxboro Evo systems. This module integrates eight independent, galvanically isolated thermocouple/mV input channels alongside a dedicated RTD reference junction compensation channel. It converts low-voltage analog signals from field sensors into digital data for the control processor, ensuring millivolt-level accuracy in demanding thermal environments. We supply this unit as 100% Brand New and Original, guaranteeing factory-certified performance for your critical control loops.

Technical Specifications

Engineering Advantages

The FBM202 P0916AC targets specific technical hurdles in industrial thermal processing:

• Eliminates Signal Cross-Talk: Individual galvanic isolation for every channel prevents ground loops and ensures that a fault on one thermocouple sensor does not corrupt data from the remaining seven inputs.

• Cold Junction Precision: The module utilizes a high-integrity 4-wire RTD for reference junction compensation. This hardware-level compensation maintains an accuracy of ±0.50°C, providing stable temperature readings even as the ambient temperature near the termination assembly fluctuates.

• Proactive Maintenance with Burnout Detection: The FBM202 features built-in upscale burnout detection. When a thermocouple wire breaks or fails, the module immediately drives the signal to full scale, triggering system alarms and preventing the controller from executing logic based on "frozen" or floating data.

• Flexible Sensor Integration: The broad millivolt range (-10.5 to +69.5 mV) allows the module to accept a wide variety of standard thermocouple types (K, J, T, E, etc.) and direct mV sources, simplifying spare parts inventory by using one module type for multiple sensor applications.

FAQs

• Does this module support cold junction compensation for all 8 channels?

  Yes. The FBM212 provides a dedicated ninth channel for an RTD reference junction. This channel measures the temperature at the terminal block to compensate for all eight thermocouple inputs simultaneously.

• Is the P0916AC compatible with older 100 Series baseplates?

  The FBM202 P0916AC belongs to the 200 Series FBM family. It requires a 200 Series modular baseplate. If you are migrating from 100 Series hardware, verify your baseplate and software revision (I/A Series v7.0 or higher recommended).

• How does the module handle high-frequency electrical noise?

  The hardware employs differential input filtering and galvanic isolation to reject common-mode noise. This ensures that EMI from nearby high-current equipment does not jitter the low-voltage thermocouple signals.

• What is the condition of this hardware?

  We guarantee this unit is 100% Brand New and remains in its original factory packaging. It has never been installed or refurbished, ensuring the full manufacturer-specified MTBF for your system.
