The Allen-Bradley 1760-MM2B is an optional memory module from the Rockwell Automation 1760 Pico Controllers series, designed for use with Series B Bulletin 1760 Pico controllers. This module connects through the Pico interface and allows the controller to write data directly to the memory module. The 1760-MM2B can store and transfer programs, important program data, and text displays generated on Series B controller screens. Unlike earlier read-only Bulletin 1760 memory modules, the 1760-MM2B supports both data storage and transfer functions, providing flexible and reliable memory management for industrial automation systems.
