Allen-Bradley 1756-M2 ControlLogix 1 MB Expansion Memory Module
The 1756-M2 is a ControlLogix expansion memory module manufactured by Allen-Bradley / Rockwell Automation. It provides 1 Mbyte word (2 MB) of non-volatile memory expansion for first-generation ControlLogix processors. By installing directly into the controller's memory expansion slot, the module expands the memory capacity available for user application logic, tag data storage, and routine execution.
Controller Compatibility and Functional Role
Designed specifically for early-generation ControlLogix processors, the 1756-M2 attaches directly to the host controller circuit board. It enhances overall memory headroom without requiring external rack slots or additional communication backplane overhead.
