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.

Hardware Overview
This chapter provides an overview of the Micro820 hardware features. It has the
following topics:
Hardware Features
Micro820 controllers are 20-point economical brick style controllers with
embedded inputs and outputs. These controllers can accommodate up to two
plug-in modules and can connect to a remote LCD (2080-REMLCD) for
configuring. The Micro820 controller also has a microSD™ card slot for project
backup and restore, and datalog and recipe.
