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://www.ab.com/manuals/gi) 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

Use this manual if you are responsible for designing, installing,

programming, or troubleshooting control systems that use

MicroLogix™ 1200 controllers.

You should have a basic understanding of electrical circuitry and

familiarity with relay logic. If you do not, obtain the proper training

before using this product.

Purpose of this Manual

This manual is a reference guide for MicroLogix 1200 controllers and

expansion I/O. It describes the procedures you use to install, wire,

and troubleshoot your controller. This manual:

•explains how to install and wire your controllers

•gives you an overview of the MicroLogix 1200 controller system

Refer to Publication 1762-RM001, MicroLogix 1200 and 1500

Programmable Controllers Instruction Set Reference Manual for the

MicroLogix 1200 and 1500 instruction set and for application examples

to show the instruction set in use. Refer to your RSLogix 500

programming software user documentation for more information on

programming your MicroLogix 1200 controller.
