FBM202 RH926EQ Foxboro Thermocouple/mV Input Module

FBM202 RH926EQ Foxboro Thermocouple/mV Input Module

The FBM202 Thermocouple/mV Input contains eight thermocouple input channels, and one isolated RTD reference junction compensation channel.

OVERVIEW

The FBM202 Thermocouple/mV Input contains eight thermocouple input channels, and one isolated RTD reference junction compensation channel (for terminal temperature sensing). Each thermocouple/mV channel accepts standard thermocouples for various temperature ranges, and each provides thermocouple burnout detection (up-scale). The inputs are galvanically isolated from other channels and ground. The module performs the signal conversion required to interface the electrical input signals from the field sensors to the optionally redundant Fieldbus. It executes an Analog Input application program, which provides integration time and Rate of Change Limits configurable options.

FEATURES

Key features of the FBM202 are:

• Eight channels for input of thermocouple signals
• One isolated RTD reference junction compensation channel (for terminal temperature sensing)
• Each input channel is galvanically isolated
• Rugged design suitable for enclosure in Class G3 (harsh) environments
• Execution of an analog input application program that provides conversion time and configurable options for Rate of Change Limits
• High accuracy achieved by sigma-delta data conversions for each channel
• Termination Assemblies (TAs) for locally or remotely connecting field wiring to the FBM202
