Foxboro 200 Series Baseplate Module Mounting

200 SERIES BASEPLATE MODULE MOUNTING

The 200 Series Fieldbus Modules mount on

200 Series baseplates which have been specially

designed to support them (see Figure 1. only vertical

baseplates shown - also FBMs do not mount on the

FCP270-only, FCM-only, or FBI-only baseplates).

The baseplates shown in Figure 1 fasten to a

structurally supported non isolated DIN rail for

mounting inside or outside an enclosure. (As an

alternative to DIN rail mounting, a mounting plate can

be used for horizontal mounting of the 200 Series

baseplate on a 19-inch rack). These baseplates can

thus be mounted in small, distributed cabinets or in a

variety of other mounting configurations.

The baseplates are backwards compatible with

existing I/O subsystems allowing for future expansion

without additional interface hardware and includes

the following:

 Primary and secondary 24 V dc power

connections

 Two Module Fieldbus connections (for A/B

Module Fieldbus daisy chain)

 Power/communication connection and field I/O

connection for each FBM

 DIP switch for baseplate identification

 A/B Module Fieldbus and optional time strobe

splitter/terminator connection

 Adding additional baseplates without removing

the system from service (requires redundant

Module Fieldbus).

The baseplates which support FBMs provide

increased overall system installation functionality by

providing unit increments of 2. 4. and 8 module

positions with various operational functionality in

combination with vertical and horizontal mounting.

Any FBM (except FBM232/233) can be removed

from a FBM-supporting baseplate without removing

or disturbing external field device wire terminations or

internal cable terminations or connections.

FCPs and FCMs require removal of wiring to the

control network.

Shielded twisted-pair cables for baseplate

interconnections are available in various lengths of

0.25 m (10 in) up to 60 m (198 ft). The maximum

twisted-pair cable length interconnecting all

baseplates is 60 m (198 ft).

Figure 1 shows selected vertical DIN rail mounted

baseplates. Horizontal DIN rail mounted baseplates

are available in similar styles as the vertical mounted

baseplates, but equivalents for each style are not all

available. Refer to PSS 31H-2SBASEPLT and

PSS 31H-2C200 B4 for additional information on the

remaining Standard and Compact 200 Series

baseplates.

FIELD I/O TERMINATIONS

Field I/O signal connections are made at termination

assemblies (TAs) mounted on DIN rails within or

external to the enclosure. Termination assemblies are

connected to the associated baseplate by dedicated

cables, which can be 0.5 m (1.7 ft) up to 30 m

100 ft) in length. These various cable lengths allow

the termination assemblies to be mounted in the

same enclosure as the FBMs, or in an adjacent

enclosure.

Analog and discrete I/O FBMs are used with specific

termination assemblies to handle a variety of

input/output signals. When used in high voltage

applications, discrete I/O termination assemblies

adapt the module to 120 V ac, 125 V dc, or 240 V ac

inputs.Termination assemblies (TAs) with built-in

relays are available for switching high voltage and

high current digital outputs. Some TAs readback the

state of the contacts to confirm the state of the relay.

INTRINSICALLY SAFE TERMINATION

ASSEMBLY – BASEPLATE (ISTA-*BP*)

The ISTA-*BP* is a combination of a baseplate with

integrated terminals fitted with one or two Fieldbus

modules (FBMs) and eight galvanic isolators. This

solution consists of a printed circuit board and

therefore does not require any additional wiring on

the board, offering a reliable interface between the

control processor and field I/O sensors and

actuators. As a result this compact packaging offers

a noticeable space saving in the interface cabinet.

This is a joint Foxboro® / Pepperl+Fuchs product.

For details, refer to PSS 31H-2Y12.

ENCLOSURES

Enclosures extend the design of the 200 Series

FBMs by providing a range of mounting options to

match application requirements.

Figure 2. Dual or Redundant ISTA-*BP*

The G-Series enclosures are floor-standing units

which accommodate 200 Series baseplates for

mounting FBMs, FEMs, FCMs, and CPs, and/or

termination assemblies or terminal blocks for
