Overview
The Differential Thermocouple/mV Input Module (FBM212) contains 14 differentiallyisolated thermocouple input channels, and one differentially isolated RTD referencejunction temperature compensation channel (for terminal temperature sensing). Eachthermocouple/mV channel accepts standard thermocouples for various temperatureranges, and each provides thermocouple burnout detection (up-scale). Each channelhas a differential input to allow voltage differences between channels withoutintroducing detected errors.
The module performs the signal conversion required to interface the electrical inputsignals from the field sensors to the optionally redundant Fieldbus. It executes ananalog input application program, which provides configurable options for ConversionTime and Rate of Change Limits.

Features
• 14 channels for input of thermocouple signals
• 1 isolated RTD reference junction compensation channel (for terminaltemperature sensing)
• Each channel has a differential input
• Rugged design suitable for enclosure in Class G3 (harsh) environments
• Execution of an analog input application program that provides conversion timeand 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 theFBM212
