COOPER P3798102-00010 CN-UIM2 Operation panel

The FBM214b has a rugged extruded aluminum exterior for physical protection of the circuits. Enclosures specially designed for mounting the Foxboro DCS Fieldbus Modules (FBMs) provide various levels of environmental protection, up to harsh environments per ISA Standard S71.04.

For high accuracy, the module incorporates a Sigma- Delta converter which can provide new analog input values for each channel every 100 milliseconds.

Light-emitting diodes (LEDs) incorporated into the front of the module provide visual indication of the module’s operational status, and communication activity on the channels.

The module can be removed/replaced without removing field device termination cabling, power, or communications cabling.

The module mounts on a 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.

Fieldbus Communication

 A Fieldbus Communication Module or a Control Processor interfaces the redundant 2 Mbps module Fieldbus used by the FBMs. The FBM214b module accepts communication from either path (A or B) of the redundant 2 Mbps fieldbus. If one path is unsuccessful or is switched off at the system level, the module continues communication over the active path. The use of an external power supply common to two or more loops requires a Cable Balun Module to maintain communication signal line balance. Termination Assemblies Field input signals connect to the FBM subsystem via DIN rail mounted TAs. The TA used with the FBM214b is described in Termination Assemblies and Cables, page 12. Configuration Tools The Compact FBM214b provides sufficient loop resistance to allow use of the HART Hand-Held Terminal or PC20 Intelligent Field Device Configurator (IFDC)

Cable Balun Module 

The Cable Balun module is used to maintain digital communication line balance for HART Transmitter to FBM loops that are powered from a common external power supply. This powering effectively connects one line of each loop together. Without the Baluns, in each loop so powered, the common connection at the external power supply, would cause near end crosstalk at the system end of the loop wiring cable. Loops using FBM internal power source do not require Baluns. The Cable Balun module contains multiple Baluns. One Balun segment is interconnected in each externally powered loop (see Cable Balun Module). There is one Cable Balun module for four channels.

NOTES:1. For detailed information on balun use and installation, see “Using the Cable Balun Module with Intelligent Transmitters” in System Equipment Installation (B0193AC). 2. Cable balun used only when multiple loops are connected to a common power supply. The FBM negative terminals connect directly to the minus (-) terminal of the power supply. The balun system side negative (-) terminals (2, 4, 6, and 8) connect to the power supply positive terminals when there are 4 (maximum) power loops. 3. For hazardous environments, install an intrinsic safety barrier such as an MTL 787S+ between the balun wiring to limit the amount of energy in the wiring. 4. A user-supplied capacitor can be installed across the external power supply(ies) to shunt AC power. 5. The external power supply can be redundant power supplies in parallel. 6. For this transmitter connection, use twisted-pair wiring inside a shielded cable with the shield grounded at the Foxboro DCS end.
