Tricon System Basic Termination Panels Introduction

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

• Analog output panels

• Pulse input panels

• Pulse totalizer input panels
