RH916XZ FBM217 - Discrete Input Module

Description

The FBM217 Discrete Input Module provides 32 input channels, each accepting a 2-wire input from a dc voltage source. Associated termination assemblies (TAs) providefor discrete inputs of under 60 V ac, 120 V ac/125 V dc or 240 V ac. The moduleperforms signal conversion required to interface the electrical input signals from thefield sensors to the Module Fieldbus.Depending on the type of I/O signal required, the TAs contain current limiting devices,high voltage attenuation circuits, optical isolation and external power sourceconnections. module can be used as a single unit, or as a redundant pair (two FBM217s).When used as a redundant pair, the modules combine to provide redundancy at theFoxboro DCS Fieldbus Module (FBM) level, with field input signals received from onecommon termination assembly though a redundant adapter affixed to the FBMs'baseplate. The field input current for redundant modules is doubled. A redundantdigital input block in the Foxboro DCS Control Software validates each input inconjunction with information to/from the module, and selects the input with the highestquality for processing in the control strategy In a redundant configuration, contact sense power from each module is diode OR'dtogether in the redundant adapter to verify redundant power. A redundant contact input function block, CINR, is used for each redundant pair ofinputs. The CINR block handles input reads and initialization logic for the redundantchannels. On each execution cycle of the CINR block, identical reads are sent to bothmodules, fully exercising the fieldbus and the logic circuitry of each module. When connected to the appropriate TAs, the FBM217 module provides functionalityformerly provided by the 100 Series FBM I/O subsystem. TAs are available whichsupport the functionality of the 100 Series main FBM07A/B, FBM08, FBM20, andFBM24A/B/C (16 input main FBMs). Expansion TAs are available for use with thesemain FBM TAs to support the functionality of expansion FBM12, FBM13, FBM21, orFBM25A/B/C (16 input expansion FBMs).

Features • 32 discrete inputs • Supports discrete input signals at voltages of:  ◦ 15 to 60 V dc  ◦ 120 V ac/125 V dc  ◦ 240 V ac • Single or redundant modules • Rugged design suitable for enclosure in Class G3 (harsh) environments • Executes the programs for Discrete Input, Ladder Logic, Pulse Count, andSequence of Events, with the configurable options: Input Filter Time and FailSafe Configuration • Various Termination Assemblies (TAs) that contain:  ◦ High voltage attenuation and optical isolation for inputs  ◦ External power connection for device excitation

Standard Design FBM217 has a rugged extruded aluminum exterior for physical protection of thecircuits. Enclosures specially designed for mounting the FBMs provide various levelsof environmental protection. Visual Indicators Red and green light-emitting diodes (LEDs) incorporated into the front of the moduleprovide visual indication of the FBM operational status, as well as the discrete statesof the individual input points. Easy Removal/Replacement The module can be removed/replaced without removing field device terminationcabling, power, or communication cabling. Redundant modules must be located in adjacent positions on the baseplate, with thefirst module located in an odd-numbered position (for example, the positions labelled"3" and "4"). To achieve redundancy, a redundant adapter module is placed on the twoadjacent baseplate termination cable connectors to provide termination for a singlecable. A single termination cable connects from the redundant adapter to theassociated termination assembly (TA). When redundant, either module may be replaced without upsetting field input signalsto the good module. The module can be removed/replaced without removing fielddevice termination cabling, power, or communications cabling.
