CM400YK Foxboro FBM9 Thermocouple Millivolt Input Module

CM400YK Foxboro FBM9 Thermocouple Millivolt Input ModuleProduct Overview The Foxboro CM400YK (FBM9) functions as a high precision interface between field mounted thermocouples millivolt sources and the I A Series Distributed Control System (DCS). This 8 channel module converts low level analog signals into digital values, providing essential data for furnace control, turbine exhaust monitoring, and chemical reactor safety. By integrating advanced filtering and Cold Junction Compensation (CJC), the CM400YK

The 8310 (Part Number: 8310) is a standard component in high-integrity safety systems:

the module switches traffic to the fiber-optic backup channel within milliseconds

The modular polycarbonate shell occupies a minimal footprint of only 8

Increased Mechanical Strength: The 11mm probe system

Fault-Tolerant Redundancy: The SCP451-51 supports bumpless failover in dual-redundant configurations

providing the precision required for grid stability and asset protection
