Allen Bradley 1785-ME32 EEPROM Storage Module

v Mark VI Series:1785-ME32

The Allen-Bradley 1785-ME32 is a dedicated EEPROM (Electrically Erasable Programmable Read-Only Memory) storage module for the PLC-5 series controllers, primarily used for PLC program backup, data storage, and system recovery. This module provides 32K words of non-volatile storage capacity, ensuring long-term preservation of control programs and critical configuration data even during power outages.

The 1785-ME32 features a rewritable design, allowing the application program from the PLC-5 processor to be copied to the EEPROM. In the event of processor memory loss, CPU replacement, or system recovery, the program can be quickly reloaded from the EEPROM, improving equipment maintenance efficiency and system reliability.

 v The 1785-ME32 offers numerous advantages:

v Non-volatile Data Storage

Utilizing EEPROM technology, PLC programs and critical parameters are reliably preserved even during prolonged power outages, preventing program loss due to battery failure.

v Fast Program Recovery

When the PLC processor is replaced or the system recovers from a failure, the program can be automatically or manually loaded directly from the EEPROM, significantly reducing downtime for maintenance.

v Rewritable and Erasable

Unlike traditional one-time ROMs, the 1785-ME32 supports multiple erasures and reprogramming, facilitating program upgrades and system optimization.

v Improved System Reliability

As a crucial backup medium for the PLC-5 system, it effectively prevents data loss due to power outages, memory failures, or battery failures, improving production continuity.

v Industrial-Grade Design

Meets the requirements of industrial automation environments, possessing excellent shock resistance, vibration resistance, and electromagnetic compatibility performance, making it suitable for long-term continuous operation in industrial settings.
