FBM203 Channel Isolated 8 Input RTD, P/N: P0914SV

The FBM203/b/c/d Platinum/Nickel/Copper RTD Input Modules contain eight resistance temperature detector (RTD) input channels.

Each input channel of the FBM203/b/c modules accepts a 2- or 3-wire RTD sensor input, within a 0 to 320 ohm (FBM203), 0 to 640 ohm (FBM203b), or 0 to 30 ohm (FBM203c) resistance range. Each input channel of the 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.

The modules perform the signal conversion required to interface the electrical input signals from the field sensors to the optionally redundant fieldbus.

The FBM203/b/c/d modules execute an analog input application program, which provides conversion time (on a per module basis) and configurable options for Rate ofChange Limits.

Two types of passive termination assemblies (TAs) are available for the FBM203/b/c modules:

• DIN rail mounted TAs, similar to those used with the other 200 Series Fieldbus Modules (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

FBM203/b/c 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.

Features of FBM203 Channel Isolated 8 Input RTD, P/N: P0914SV

• Eight resistance temperature detector (RTD) input channels

• Each analog input 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 FBM203/b/c/d

High Accuracy

For high accuracy, each channel incorporates a Sigma-Delta converter which can provide new analog input values for each channel every 25 ms, and a configurable integration period to remove any process noise and power line frequencies. Each time period, the FBM converts each analog input to a digital value, averages these values over the time period and provides the averaged value to the controller.

Standard Design

FBM203/b/c/d have a rugged extruded aluminum exterior for physical protection of the circuits. Enclosures specially designed for mounting the FBMs provide various levels of environmental protection, up to harsh environments, per ISA Standard S71.04.

Visual Indicators

Red and green light-emitting diodes (LEDs) incorporated into the front of the modules provide visual status indications of FBM functions.

Easy Removal/Replacement

The module mounts on a DIN rail mounted modular baseplate, which accommodates up to four or eight FBMs. The modular baseplate is either DIN rail mounted or rack mounted, and includes signal connectors for redundant Fieldbus, redundant independent dc power, and termination cables.
