Preface
About This Publication Use this manual if you are responsible for designing, installing, programming,
or troubleshooting control systems that use Micro800™ 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.
This manual is a reference guide for Micro800 controllers, plug-in modules,
and accessories. 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 Micro800 controller system
See the Online Help provided with Connected Components Workbench™
software for more information on programming your Micro800 controller.

Chapter 1 Hardware Overview
Hardware Features Micro830, Micro850, and Micro870 controllers are economical brick style
controllers with embedded inputs and outputs. Depending on the controller
type, it can accommodate from two to five plug-in modules. The Micro850 and
Micro870 controllers have expandable features. The Micro850 controller can
support up to four expansion I/O modules and the Micro870 controller can
support up to eight expansion I/O modules.
The controllers also accommodate any class 2 rated 24V DC output power
supply that meets minimum specifications such as the optional Micro800
power supply.
See Troubleshooting on page 303 for descriptions of status indicator operation
for troubleshooting purposes.
