Foxboro PSS 21H-2W6 B4 DIN Rail Mounted Modular Baseplates

The DIN rail mounted Modular Baseplates provide the mounting platform and communication backplane for DIN rail mounted modules.

FEATURES

Key features of the Modular Baseplates are:

 2, 4, and 8 module positions in combination with

vertical and horizontal mounting

 Connection for optional GPS time strobe for

FCP280, FCP270, and FCM100Et

 Connection to the 2 Mbps Module Fieldbus for

the DIN rail mounted Fieldbus Modules, or to a

268 Kbps Fieldbus for the 100 Series FBMs

 Primary and secondary 24 V dc power and

communications connections

 Field connection for I/O termination assemblies,

redundant adapters and module identifiers for

each module

 Splitters/terminators for time strobe and A/B

Fieldbus

 DIP switch for identification of certain Modular

Baseplates

 Backwards compatibility with existing DIN I/O

subsystems allowing for future expansion without

additional interface hardware

 Adding additional Modular Baseplates without

removing the system from service (requires

redundant bus)

 Keyed positions dedicated to FCP270 or

FCM/FBM only

 Passive backplane to increase system reliability.

OVERVIEW

The Modular Baseplates enable overall system

installation functionality by providing unit increments

of 2, 4, and 8 module positions in combination with

vertical and horizontal mounting.

These Modular Baseplates support distributed

control for both small and large systems and

specifically support the following I/A Series® system

DIN rail mounted modules:

 Field Control Processor 280 (FCP280) faulttolerant

or non-fault-tolerant

 Field Control Processor 270 (FCP270) faulttolerant

or non-fault-tolerant

 Field Communications Modules (FCM100Et and

FCM100E) and other FCMs

 Fieldbus Expansion Modules (FEM100E)

 Fieldbus Isolator/Filter Modules (FBI100)

 DIN rail mounted Fieldbus Modules (FBMs) and

100 Series FBMs connection.

MODULAR BASEPLATE MOUNTING

Most Modular Baseplates are available in two basic

mounting configurations — horizontal DIN rail mount

(see Figure 1) or vertical DIN rail mount (see Figure 2).

Either of these mounting configurations can be

employed internal to an enclosure, external to an

enclosure, or mounted on a secure DIN rail.
