P0922UD Platinum/Nickel/Copper RTD Input Modules

The Compact FBM203/c/d Platinum/Nickel/Copper RTD Input Interface Modules
contain eight resistance temperature detector (RTD) input channels.
Each input channel of the Compact FBM203/c modules accepts a 2- or 3-wire RTD
sensor input, within a 0 to 320 ohm (FBM203), or 0 to 30 ohm (FBM203c) resistance
range. Each input channel of the Compact FBM203d accepts a 4-wire RTD sensor
input, within a 0 to 320 ohm resistance range. Each analog input is galvanically
isolated from other channels and ground. It is part of the Compact 200 Series I/O
subsystem described in Compact 200 Series I/O Subsystem Overview
(PSS 41H-2COV).
The modules perform the signal conversion required to interface the electrical input
signals from the field sensors to the optionally redundant fieldbus.
The Compact FBM203/c/d modules execute an analog input application program,
which provides conversion time (on a per module basis) and configurable options for
Rate of Change Limits.
TAs are available for FBM203c, which support the functionality of the 100 Series
FBM33A when used with a 3-wire RTD input.
TAs are available for FBM203d, which support the functionality of the 100 Series
FBM03B or FBM33B when used with a 2-wire or 4-wire RTD input.
