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://www.rockwellautomation.com/literature/) 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.

No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software

described in this manual.

Overview

Introduction

Module Description

The module converts digital data from controllers to provide analog

output data. The module provides the following output types and

ranges.

The data can be configured as:

•engineering units.

•scaled-for-PID.

•percent range.

•raw/proportional data.

Module configuration is normally done via the controller’s

programming software. In addition, some controllers support

configuration via the user program. In either case, the module

configuration is stored in the memory of the controller. Refer to your

controller’s user manual for more information.
