Triconex AI2361 7400210-020 Analog Input Card Module

Basic Termination Panels

Basic termination panels are a low-cost means of connecting field wiring to a Tricon. Basic

termination panels allow you to marshal field signals in a separate enclosure up to 99 feet (30

meters) from a Tricon chassis.

A basic termination panel consists of a PCB—with panel connector and terminal blocks—

mounted on a DIN rail-compatible plastic housing. The housing snaps onto mounting rails in

accordance with DIN 50 022. Current-to-voltage conversion resistors are also mounted on

analog input panels configured for current input. You must provide any other components

required for your application.

The panel connector and terminal blocks are directly interconnected via the PCB. The

compression terminals on the terminal blocks are designed for use with 24- to 12-gauge (0.3

mm2 to 2.1 mm2) wiring.

Refer to Appendix B, Fanned-Out Cable Pinouts for signal labels and connector pin numbers.

Each signal label indicates the corresponding screw terminal on the termination panel. The

panel connector’s pin numbers match those on the Tricon backplane’s connector.

A basic termination panel is packaged with a cable that connects between a Tricon chassis

backplane and the basic termination panel. A female connector on one end of the cable is keyed

to match the male connector on the Tricon backplane. A male connector on the opposite end of

the cable is keyed to match the male connector on the termination panel.

Basic termination panels are available in these configurations:

• Digital input panels

• Digital output panels

• Relay output panels

• Analog input panels

RG 1.180 Termination Panels

RG 1.180 termination panels are suitable for use in applications that need to meet the

requirements of Regulatory Guide 1.180. “Guidelines for Evaluating Electromagnetic and

Radio-Frequency Interference in Safety-Related Instrumentation and Control Systems, Revision

1” published by the U.S. Nuclear Regulatory Commission.

Hazardous Location (Nonincendive) Termination Panels

Hazardous location (nonincendive) termination panels are suitable for use in Zone 2. and Class

1. Division 2 field circuits. These panels contain extra circuitry designed to limit power available

to the field terminals and have been examined and certified by TÜV Rheinland as being

nonincendive. This guarantees that if the field wires are accidentally opened, shorted, or
