　　FBM227, 0 to 10 V DC, Contact/DC I/O Module with DPIDA and MDACT Support

　　OVERVIEW

　　The FBM227 module provides signal conversion required to interface analog and digital electrical input/output signals from field sensors/actuators. It has four 0 to 10 V DC analog input channels and two 0 to 10 V DC analog output channels, all of which are individually isolated. For the digital I/O signals (on/off state), it has four digital input channels, isolated in two groups of two channels each, and four digital, pair isolated, output channels.It executes either the Analog I/O or Digital I/O application program, and has support for MDACT or DPIDA control.

The configurable options for each analog program are Input Resolution, Fail-safe Configuration (Hold/Fallback) and Output Fail-safe Fallback Data. The configurable options for each digital program are Input Filter Time, Fail-safe Configuration, Fail-safe Fall Back and Sustained or Momentary Outputs. If the Momentary Output configuration is selected, then Pulse Output Interval is also configurable.Configurable options for inputs are exercised on a per module basis; those for outputs are exercised on a per channel basis.

　　STANDARD DESIGN

　　The FBM227 module has 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.

　　EASY REMOVAL/REPLACEMENT

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

　　VISUAL INDICATORS

　　Light-emitting diodes (LEDs) incorporated into the front of the modules provide visual status indications of Fieldbus Module (FBM) functions.

　　MODULAR BASEPLATE MOUNTING

　　The modules mount on a modular baseplate or conversion mounting structure 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 communications with the FBM227 over the redundant 2 Mbps module Fieldbus used by the FBMs. The FBM227 module accepts communication from either path (A or B) of the redundant 2 Mbps fieldbus – should one path fail or be switched off at the system level, the module continues communication over the active path.

　　TERMINATION ASSEMBLIES

　　Field I/O signals connect to the FBM subsystem via DIN rail mounted TAs. The TAs used with the FBM227 modules are described in “TERMINATION ASSEMBLIES AND CABLES” on page 8.

　　Input Channel Isolation

　　The FBM’s analog channels are channel isolated from all other channels and earth (ground). The FBM’s digital channels are isolated in pairs from all other channels and earth (ground). The module/TA withstands, without damage, a potential of 600 V AC on the analog channels or 1250 V AC on the digital channels(1) (see notes below) applied for one minute between any channel and ground, or between a given channel and any other channel.

　　TERMINATION ASSEMBLIES AND CABLES

　　Field signals connect to the FBM subsystem via DIN rail mounted Termination Assemblies. TAs for the FBM227 module are available in the following forms:

　　Compression screw type using Polyamide (PA) material See “FUNCTIONAL SPECIFICATIONS – TERMINATION ASSEMBLIES” below for a list of TAs used with the FBM227 modules

　　A removable termination cable connects the DIN rail mounted TA to the FBM via a field connector on the baseplate in which the FBM is installed. Termination cables are available in the following materials:

　　Polyurethane   Low Smoke Zero Halogen (LSZH). Termination cables are available in a variety of lengths, up to 30 meters (98 feet), allowing the Termination Assembly to be mounted in either the enclosure or in an adjacent enclosure. See Table 3 for a list of termination cables used with the TAs for the FBM227 modules.
