Rockwell Automation announces the new Allen-Bradley Micro820 programmable logic controller (PLC), a new addition to the Allen-Bradley Micro800 PLC family. The 20-point Micro820 controller features embedded Ethernet and serial ports, and a microSD slot. Pulse-width modulation (PWM) output and recipe management makes it ideal for small machines, such as stretch wrappers and compressor control. Data logging, analog and thermistor temperature inputs are essential for remote automation applications, including water-pump control and air-handling units. Connected Components Workbench software simplifies the configuration, design and maintenance of the Micro820 controller. The latest version of the software adds support for additional machine devices, like the new Allen-Bradley Guardmaster 440C-CR30 configurable safety relay and Allen-Bradley Kinetix 3 component servo drive. This release also provides password protection for application code, and improved investment protection via a friendly controller upgrade tool and multiple project sessions to collaborate between them. For those new to building machines, the software is a free download and offers built-in tutorials, manuals and user assistance.
