Product Description
The Rockwell Automation 1764-MM2 is a 16KB memory module for the Micrologix 1500 series programmable controllers. Featuring a NEMA Type IP20 (open) enclosure, it requires protection from dust and corrosive environments. It offers relay port and DC FET output sources, real-time clock communication, and diagnostic capabilities. Operating temperature should be maintained between 0 and 55 degrees Celsius, and storage temperature between -40 and 85 degrees Celsius, to avoid performance degradation and reduced lifespan. The module mounts within the Micrologix controller, providing additional memory and recall functions, and its presence is indicated by a hardware LED located between the status LED and the battery on the controller, which has either 24 or 28 embedded I/O points.
Is Your Device Showing These Signs?
The Allen Bradley 1764-MM2 MicroLogix 1500 memory module commonly experiences issues such as memory corruption leading to PLC faults, program loss requiring memory module replacement or reprogramming, and failure to retain data after power cycles indicating a need for battery replacement or module repair. Corrupted firmware also necessitates reflashing the memory module, and physical damage from electrostatic discharge or environmental factors results in operational failure. Compatibility problems with specific MicroLogix 1500 series PLCs are resolved through firmware upgrades or ensuring correct module revision levels.
