Allen-Bradley 1756-L55 ControlLogix Processor

The Allen-Bradley 1756-L55 ControlLogix Processor is a high-performance CPU for Rockwell Automation's ControlLogix platform, engineered to run complex control logic in large distributed automation systems. This kit pairs the L55 processor with a 1756-M13 memory module and a key, enabling onboard program storage and straightforward deployment in a compatible ControlLogix chassis. The 1756-L55 is part of the Series A ControlLogix line and supports firmware version 16.023, reflecting its mid-generation capability within the platform. Typical applications include process control, manufacturing line automation, material handling, and packaging systems that require deterministic CPU performance and integrated data handling with support for a wide range of I/O and communications options in the ControlLogix ecosystem.
