FOXBORO FBM219 RH916RH Discrete I/O Module
OVERVIEW
The FBM219 Discrete I/O Module has 24 discrete
input channels and 8 discrete output channels.
Associated termination assemblies (TAs) support
discrete input or output signals at voltages of under
30 V dc, 120 V ac/125 V dc, or 240 V ac.
Depending on the type of I/O signal required, the TAs
contain current limiting devices, fuses, relays, or relay
outputs with internal or external power source and
fusing.
TAs are available which support the functionality of
the 100 Series main FBM07A/B, FBM08. FBM20.
and FBM24A/B/C (16 input main FBMs), when these
main FBMs are used with expansion FBM14.
FBM15. FBM16. FBM27 or FBM42 (8 input/8/output
expansion FBMs).
FEATURES
Key features of the FBM219 are:
Twenty-Four (24) discrete inputs
Eight (8) discrete outputs
Supports discrete input/output signals at
voltages of:
• 15 to 60 V dc
• 120Vac/125 V dc
• 240V ac
Each input/output is group isolated
Compact, rugged design suitable for enclosure in
Class G3 (harsh) environments
Executes the Discrete I/O or Ladder Logic
program, with the following configurable options:
Input Filter Time, Fail Safe Configuration, Fail
Safe Fall-Back, and Sustained or Momentary
FBM219
Outputs
Various Termination Assemblies (TAs) that contain
high voltage attenuation and optical isolation for
inputs
COMPACT DESIGN
The module has a compact design, with 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
Light-emitting diodes (LEDs) incorporated into the
front of the module provide visual indication of the
Fieldbus Module operational status, as well as the
discrete states of the individual input and output
points.
EASY REMOVAL/REPLACEMENT
The module can be removed/replaced without
removing field device termination cabling, power, or
communication cabling.
FIELDBUS COMMUNICATION
A Fieldbus Communications Module or a Control
Processor interfaces to the redundant 2 Mbps
module Fieldbus used by the FBMs. The FBM219
accepts communication from either path (A or B) of
the 2 Mbps Fieldbus- should one path fail or be
switched at the system level, the module continues
communication over the active path.
MODULAR BASEPLATE MOUNTING
The module mounts on a DIN rail mounted baseplate,
which accommodates up to four or up to eight
Fieldbus Modules. The Modular Baseplate is either
DIN rail mounted or rack mounted, and includes
signal connectors for redundant Module Fieldbus,
redundant independent dc power, and termination
cables.
SECURITY
Field power for contacts or solid state switches is
current limited.
TERMINATION ASSEMBLIES
Field I/O signals connect to the FBM subsystem via
DIN rail mounted TAs. The TAs used with the
FBM219 are described in See “TERMINATION
ASSEMBLIES AND CABLES” on page 7.
