Foxboro P0916BX Termination Assembly

Features

• Supports discrete input signals at voltages of:

◦ 15to60VDC

◦ 120VAC/125VDC

◦ 240VAC

• Single or redundant modules

• Ruggeddesignsuitable for enclosure in Class G3 (harsh) environments

• Executes the programs for Discrete Input, Ladder Logic, Pulse Count, and

Sequence of Events, with the configurable options: Input Filter Time and Fail

Safe Configuration

• Various Termination Assemblies (TAs) that contain:

◦ Highvoltage attenuation and optical isolation for inputs

◦ External power connection for device excitation

Standard Design

FBM217hasarugged extruded aluminum exterior for physical protection of the

circuits. Enclosures specially designed for mounting the FBMs provide various levels

of environmental protection.

Visual Indicators

Red andgreen light-emitting diodes (LEDs) incorporated into the front of the module

provide visual indication of the FBM operational status, as well as the discrete states

of the individual input points.

Easy Removal/Replacement

The module can be removed/replaced without removing field device termination

cabling, power, or communication cabling.

Redundant modules must be located in adjacent positions on the baseplate, with the

first module located in an odd-numbered position (for example, the positions labelled

“3” and “4”). To achieve redundancy, a redundant adapter module is placed on the two

adjacent baseplate termination cable connectors to provide termination for a single

cable. A single termination cable connects from the redundant adapter to the

associated termination assembly (TA).

Whenredundant, either module may be replaced without upsetting field input signals

to the good module. The module can be removed/replaced without removing field

device termination cabling, power, or communications cabling
