FOXBORO FBM02 FBM05 FBM07 Product Brief Description

The FOXBORO FBM02 is a legacy 100-series 8-channel thermocouple/mV analog input fieldbus module for Foxboro I/A Series DCS. It acquires weak millivolt signals from various thermocouple types and low-level mV transducers, performs cold junction compensation, analog-to-digital conversion, and transmits digital data to control processors via redundant fieldbus. It is designed for temperature measurement applications and is the predecessor of the upgraded FBM202 module.

Product Features

• 8 galvanically isolated input channels for thermocouple and low-level mV signals
• Built-in automatic cold junction compensation to eliminate temperature measurement drift
• Thermocouple burnout detection, open-circuit and signal out-of-range diagnostics per channel
• Configurable digital filter for noise suppression and rate-of-change alarm setup
• Redundant fieldbus communication interface for reliable real-time data exchange with CP controllers
• Plug-in rack-mounted unit with front LED indicators for status and fault troubleshooting

Application Scenarios

• Petrochemical and chemical plant furnace, reactor and pipeline temperature monitoring
• Oil & gas processing thermal process temperature measurement loops
• Power plant boiler, turbine and auxiliary equipment thermocouple signal collection
• Pulp & paper, pharmaceutical manufacturing thermal process monitoring
• Legacy Foxboro I/A Series DCS spare temperature I/O module replacement and retrofit
