Physical Specifications

FBM217 Termination Assembly

Mounting The FBM217 mounts on a modular

baseplate. The baseplate can be mounted

on a DIN rail (horizontally or vertically), or

horizontally on a 19-inch rack using a

mounting kit. Redundant modules must be

located in odd and even adjacent positions

on the baseplate (positions 1 and 2, 3 and 4,

5 and 6, or 7 and 8) along with the

appropriate redundancy adapter.

See Standard 200 Series Baseplates (PSS

41H-2SBASPLT) for details. Alternatively, a

non-redundant FBM217 mounts on a 100

Series conversion mounting structure. See

100 Series Conversion Mounting Structures

(PSS 41H-2W8) for details.

The TA mounts on a DIN rail and

accommodates multiple DIN rail styles

Termination Assemblies and Cables

Field I/O signals connect to the FBM subsystem via DIN rail mounted termination

assemblies (TAs). Multiple types of TAs are available with FBM217 to provide input

signal connections, signal conditioning, optical isolation from signal surges and

external power connections for field devices. Since these features are built into the

termination assemblies (where required), in most applications there is no need for

additional termination equipment for field circuit functions such as circuit protection or

signal conditioning (including fusing and power distribution).

The termination assembly can be used with a single FBM217 or with a redundant pair

(two FBM217s).

The DIN rail mounted termination assemblies connect to the FBM subsystem

baseplate by means of removable termination cables. When used with a redundant
