FBM202 P0926EQ FOXBORO Channel Isolated 8 Input

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.

Two types of passive termination assemblies are available for the FBM202:

• DIN rail mounted TAs, similar to those used with the other 200 Series FBMs.
• Baseplate-mounted TA, which mounts directly onto the field I/O connectors of the 200 Series baseplate. These TAs provide field I/O wiring support for two FBM202s in paired slots (that is, in positions 1 and 2, 3 and 4, 5 and 6, or 7 and 8), as shown in Figure 1.
