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.

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 and can additionally 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.
