Product Overview
The 1756-L55M23 is a Series A ControlLogix processor module by Allen-Bradley (Rockwell Automation). It combines data and logic memory in a single package and serves as the central CPU in a Logix5000 control system. It executes logic, handles I/O, and manages program scan tasks. Typical applications include medium-scale industrial control installations requiring precise logic execution and I/O management in manufacturing, processing, or machine control environments. The 1756-L55M23 is designed for integration in standard ControlLogix chassis.
