Triconex AI3351 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
