User Manual

Important User Information

Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application,

Installation and Maintenance of Solid State Controls (publication SGI-1.1 available from your local Rockwell Automation sales office or online at

http://literature.rockwellautomation.com) describes some important differences between solid state equipment and hard-wired electromechanical

devices. Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons responsible for applying this

equipment must satisfy themselves that each intended application of this equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use or application of this

equipment.

The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and requirements associated

with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for actual use based on the examples and

diagrams.

Who Should Use This

Manual

We assume that you have previously used an Allen-Bradley programmable

controller, that you are familiar with its features, and that you are familiar with

the terminology we use. If not, read the user manual for your processor before

reading this manual.

Purpose of the Manual

This manual is a reference guide for the FLEX I/O Thermocouple, RTD,

Millivolt Input Modules. It describes the procedures for installing, configuring

and troubleshooting your module. For more information, consult the

following chapters.

About the Vocabulary

This manual covers the 1794-IRT8, 1794-IRT8K, and 1794-IRT8XT modules,

which are identical, except that the 1794-IRT8K is conformally coated.

In this manual, we refer to:

• the individual Thermocouple, RTD, and mV module as the “module,”

or “TC, RTD, and mV module.”

• the programmable controller as the “controller” or the “processor.”
