FBM207 P0914TD analog input module

The FBM207 P0914TD is an analog input module designed for Foxboro’s I/A Series Distributed Control System (DCS). It specializes in acquiring and processing analog signals from on-site sensors, serving as a critical front-end component for real-time process monitoring in industrial scenarios. Below is its detailed information:

1. Core Functions

High-Precision Analog Signal Acquisition: It mainly collects low-level analog signals such as thermocouple (TC) and resistance temperature detector (RTD) signals, as well as standard 4-20mA current signals or 0-10V voltage signals.
Signal Conversion & Transmission: Converts the acquired continuous analog signals into digital signals recognizable by the DCS. It then transmits the digital signals to the upper-level control system for data analysis, process monitoring, and logic control.
Built-In Signal Conditioning: Integrates functions like cold junction compensation (for thermocouples) and lead resistance compensation (for RTDs) to reduce environmental interference and ensure the accuracy of temperature or process parameter measurement.
