The DIN rail mounted Fieldbus Module baseplate

provides a convenient, secure facility for the mounting

of DIN rail mounted Fieldbus Modules (FBMs) and

Fieldbus Communications Modules (FCMs). Its eight

mounting positions can accommodate up to eight

FBMs or a combination of FBMs and FCMs.The

baseplate also provides the necessary connectors for

redundant power, redundant module Fieldbus, and

termination cables.

PLUG-IN MODULES

The DIN rail mounted FBMs accommodated by the

baseplate are compact, plug-in modular assemblies

used to interface field devices with the host control

station. The FCMs, having the same form factor as

the FBMs, perform signal interface functions.

For example, FCM10Es are used to interface the

Ethernet trunk Fieldbus with the 2 Mbps module

Fieldbus, and FCM2Fs are used for fiber optic

communications extensions between baseplates. The

FBMs and FCMs plug onto the baseplate by means

of their two, 48-pin connectors, and each is fastened

in place by two screws.
