1785-ME32 Allen-Bradley Enhanced PLC-5/30 EEPROM Memory Module

Product parameters

Module type: EEPROM (Electrically Erasable Programmable Read-Only Memory) storage module

Storage capacity: 32K words, used for storing user programs and data

Compatible processors: PLC-5 series processors, including but not limited to:

1785-L20B, 1785-L30B, 1785-L40B, 1785-L40L, 1785-L60B, 1785-L60L

1785-L80B, 1785-L80C (the processors you mentioned earlier)

Other PLC-5 enhanced processors (such as 1785-L26B, 1785-L46B, etc.)

Storage type: Non-volatile storage, supporting the permanent preservation of programs and data

Write/erase cycle: EEPROM supports a limited number of write/erase cycles (typically 10,000 times), so frequent writes should be handled with caution

Installation location:

Insert the dedicated storage module slot for the PLC-5 processor (usually located on the front of the processor module)

It does not occupy the slot of the 1771 I/O rack

Power consumption: No additional backplane current requirement

Operating temperature: 0 to 60°C (32 to 140°F)

Storage temperature: -40 to 85°C (-40 to 185°F)

Relative humidity: 5% to 95% (no condensation)

Environmental protection: Open enclosure (IP00), must be installed in a cabinet that complies with NEMA standards to protect against dust, moisture or corrosive gases

Certification: Complies with CE, UL, CSA and other standards (consistent with the certification of processor modules)

Indicator: There is no independent status indicator light. It relies on the status display of the processor module

Function

Non-volatile storage

It provides 32K words of non-volatile storage space for saving user programs, ladder diagram logic, data tables and configuration data, which can retain data even in the event of power failure or battery failure.

Avoid relying on battery backups (such as 1770-XYC lithium batteries) to enhance system reliability.

Program Backup and recovery

Support writing the RAM content of the PLC-5 processor (such as 1785-L80C) to 1785-ME32, or loading it from 1785-ME32 into the processor RAM for convenient program backup, recovery or cross-device migration.

Perform storage operations through programming software (such as RSLogix 5 or Studio 5000 Logix Designer).

Fast program loading

It allows for the rapid loading of pre-stored programs into the processor, reducing system startup time and is suitable for scenarios where programs need to be frequently replaced.

Modular design

Insert directly into the storage module slot of the PLC-5 processor without the need for additional wiring or backplane power supply, simplifying installation and maintenance.

Compatibility

Compatible with a variety of PLC-5 processors and suitable for Enhanced, ControlNet and Ethernet series processors.

It supports use in conjunction with 1771 I/O racks and modules to build a complete control system.

Data protection

EEPROM technology ensures that data is not lost after power failure, making it suitable for long-term operation or critical mission applications.

It can be protected through the processor Settings program (such as prohibiting changes) to prevent unauthorized modifications.

Application scenarios

Manufacturing plant

In automotive manufacturing, food processing or electronic assembly production lines, complex ladder diagram programs are stored to ensure that the control logic remains intact after power failure or battery replacement.

Supports rapid program switching and is suitable for flexible configuration on multi-product production lines.

Process control

In the chemical, oil and gas or pharmaceutical industries, key process control programs are preserved to ensure system reliability.

It is suitable for scenarios that require long-term storage of data tables, such as formula management or historical records.

Energy Management

In power distribution or renewable energy systems, control logic and configuration data are stored to ensure the stable operation of switchgear or monitoring devices.

Suitable for critical mission environments, it reduces the risk of program loss caused by battery failure.

Material handling

In warehousing or logistics systems, control programs for automated sorting, conveying or stacking equipment are saved to support rapid system recovery.

Legacy system maintenance

It is used to maintain the old system based on PLC-5 and extend the system life through EEPROM storage.

It is suitable for backing up old system programs and preparing for migration to modern platforms such as ControlLogix.

Remote or harsh environments: In remote facilities or harsh environments (such as high temperature, low temperature or high humidity), EEPROM offers a more reliable storage solution than battery backup.
