Preface

Publication 17946.5.2 - May 1996

Using This Manual

This manual shows you how to use your FLEX I/O Analog modules

with Allen-Bradley programmable controllers. The manual helps you

install, program and troubleshoot your modules.

You must be able to program and operate an Allen-Bradley

programmable controller to make efficient use of your FLEX I/O

modules. In particular, you must know how to program block

transfers.

We assume that you know how to do this in this manual. If you do

not, refer to the appropriate programming and operations manual

before you attempt to program your modules.

In this manual, we refer to:

–the analog input or analog output module as the “input

module” or ‘‘output module”

–the Programmable Controller as the “controller”

This manual is divided into five chapters. The following chart lists

each chapter with its corresponding title and a brief overview of the

topics covered in that chapter.

Overview of FLEX I/O and your

Analog Modules

In this chapter, we tell you about:

•what the FLEX I/O system is and what it contains

•types of FLEX I/O analog modules

•how FLEX I/O analog modules communicate with programmable

controllers

•the features of your analog modules

FLEX I/O is a small, modular I/O system for distributed

applications that performs all of the functions of rack-based I/O. The

FLEX I/O system contains the following components shown below:

•adapter/power supply – powers the internal logic for as many as

eight I/O modules

•terminal base – contains a terminal strip to terminate wiring for

two- or three-wire devices

•I/O module – contains the bus interface and circuitry needed to

perform specific functions related to your application
