The Allen-Bradley 2080-LC50-48AWB Micro850 Programmable Controller is an industrial PLC from Rockwell Automation's Micro850 family. It was developed for compact machine-control systems requiring a relatively large number of discrete I/O points, Ethernet connectivity, and relay-based output switching.
Its onboard configuration consists of 28 digital inputs designed for 120V AC signals and 20 relay outputs. This combination makes it suitable for industrial equipment that monitors AC input signals and controls external devices through relay contacts. The controller also provides embedded Ethernet, RS-232, and RS-485 interfaces for communication with compatible automation equipment.
The Micro850 platform supports five plug-in slots for compatible accessories and can be expanded with supported Micro800 I/O modules. Its USB programming interface and Connected Components Workbench engineering environment provide options for application development, configuration, and maintenance.
An important consideration for buyers and maintenance engineers is the product's lifecycle status. The 2080-LC50-48AWB was discontinued by Rockwell Automation on July 31, 2023. The manufacturer identifies the 2080-L50E-48AWB as its functional replacement. For existing installations, the original controller remains relevant to maintenance and spare-parts requirements, while new projects should evaluate the replacement model and verify system compatibility before migration.
