Allen-Bradley 1763-MM1 Memory Module

Allen-Bradley 1763-MM1 Memory Module is a 128 KB EEPROM memory expansion for MicroLogix 1100 programmable logic controllers. It provides nonvolatile storage for the controller’s program and data, ensuring code and variable values survive power cycles and enabling more ambitious ladder logic implementations. The module offers 128 KB of additional memory and supports Real-Time Clock operation, opening possibilities for time-stamped data logging and RTC-based timing features within supported MicroLogix 1100 configurations. Catalog number 1763-MM1 is Allen-Bradley’s official memory-module option for the MicroLogix 1100 family, designed to augment on-board memory without replacing the controller. In a MicroLogix 1100 system, the 1763-MM1 increases memory headroom for larger programs and longer data retention, helping engineers scale automation projects with a single, standardized expansion accessory.
