The Foxboro FBM212 P0914XL 14-channel thermocouple Input module is a high-performance, industrial-grade thermocouple input module designed to handle temperature measurements in complex industrial environments. Here is a detailed breakdown of the component:

I. Product overview

Model: FBM212 P0914XL

Manufacturer: Foxboro (Invensys Group)

Type: Thermocouple /mV input module

Main Features: 14 differential isolated thermocouple input channels, and one differential isolated RTD reference junction temperature compensation channel (for terminal temperature sensing).

Second, technical specifications and characteristics

Input channel:

Quantity: 14 differential isolated thermocouple input channels

Compatibility: Standard thermocouples in various temperature ranges are accepted

Function: Each channel provides thermocouple burn detection (upper range) function

RTD reference junction compensation channel:

Quantity: 1

Purpose: For terminal temperature sensing, to provide high precision temperature compensation

Signal conversion:

Perform the required signal conversion from the field sensor to the electrical input signal interface of the optional redundant fieldbus.

Provides configurable options for conversion time and rate of change limits.

High precision:

High precision is achieved through sigma-delta data conversion on each channel.

Integrated multiplexed Sigma-Delta converters provide new analog input readings every 500 milliseconds and can be configured for integration cycles to eliminate process noise and power line frequency interference.

Rugged and durable:

Rugged design for enclosures in G3 (harsh) environments.

The extruded aluminum housing provides physical protection for the circuit and complies with ISA standard S71.04, providing varying degrees of environmental protection.

Connection and installation:

The Terminal Component (TAs) supports local or remote connection of field cabling to the FBM212.

Modules are mounted on the 200 Series baseplate and can accommodate up to four or eight fieldbus modules.

The base plate can be mounted on a DIN rail or rack and includes signal connectors for redundant fieldbuses, redundant independent DC power supplies and terminal cables.
