ASSEMBLY

DESCRIPTION

The 40-channel T8830 Trusted

Field

Termination Assembly (FTA) is the primary

interface between the Trusted

TMR Analog

Input module and the field device (wiring) loop.

The FTA is supplied with 250 dropping

resistors, suitable for 4-20mA current loops.

The FTA is made up of several components:

the interface cable connector and hood lock,

loop power distribution, dropping resistors, and

field input terminations.

To reduce integration time, the interface cable

which connects the FTA and its I/O module is

pre-assembled and fitted with a pair of

specialized hoods. These hoods are used to

secure the cable in place. The FTA hood fits

into the metal slot retainer shown in the

illustration at left.

To facilitate the need for on-line

replacement of an unhealthy I/O

module, the interface cable is designed

to provide the user with two different

methods for on-line maintenance. The

first method involves the use of a dual

connector hood. The dual connectors

allocate an adjacent slot in the

Trusted

chassis for a hot-replacement

module. Refer to Figure 1 below for

more details regarding a dedicated

spare slot approach.

The second method of hot replacement

uses a “one-to-many” approach. This

feature is called the SmartSlot Link

(SSL). The SSL furnishes the method

to use a single I/O module slot as a hot

replacement slot. This configuration

reduces I/O chassis space by using a

single slot for hot replacement of all

modules of that type. In this case the I/O

cable has a second socket on the back

of the module end for connecting a

cable to the hot replacement slot.
