Allen-Bradley 1775-MEA PLC-3 Memory Module
The Allen-Bradley 1775-MEA is a dedicated 64K RAM memory module designed for the PLC-3 programmable logic controller platform. It provides high-reliability program and data storage featuring built-in error-correcting memory logic to prevent data corruption during continuous industrial operations. Operating as an expansion memory unit within the 1775 system rack, the 1775-MEA ensures steady execution of control routines in heavy-duty automation setups.
Functional Role & Memory Architecture
Memory stability is critical in large-scale PLC-3 system architectures. The 1775-MEA delivers 64 kilobytes of RAM equipped with Error-Correcting Code (ECC) functionality. This feature automatically detects and corrects single-bit memory errors in real time while detecting multi-bit errors, protecting critical control logic, recipes, and system variables from bit flips caused by noise or transient interference.
System Compatibility & Hardware Specifications
The module installs directly into compatible expansion slots of the Allen-Bradley PLC-3 controller chassis. Designed as a ruggedized industrial module, it interfaces directly with the system backplane for power distribution and high-speed data exchange with the central processor unit.
