32K EEPROM Memory Module 1785-ME32 for PLC-5 Backup

Product Overview

Allen-Bradley 1785-ME32 is a 32K-word EEPROM memory module used for non-volatile program backup on enhanced PLC-5 and Ethernet PLC-5 processors. It allows the user program to be stored and restored without relying solely on battery-backed RAM.

Technical Specs

• Capacity: 32K words
• Type: EEPROM (electrically erasable programmable ROM)
• Function: Program backup / non-volatile storage
• Compatible processors: Enhanced PLC-5 series (PLC-5/11, /20, /30, /40, /60, /80 and Ethernet variants)
• Write protection: Jumper selectable
• Operating temperature: 0 °C to 60 °C
• Weight: Approx. 71 g

Key Features

• Non-volatile storage of the complete user program
• Supports repeated erase/write cycles
• Write-protection jumper for security
• Simple plug-in installation into the processor memory slot

FAQ

• Capacity? 32K words.
• Use? Program backup for PLC-5 processors.
• Compatible with? Enhanced and Ethernet PLC-5 series.

Installation Guide

1. Power down the processor and remove it from the chassis if required.
2. Insert the 1785-ME32 into the memory module slot on the processor.
3. Set the write-protection jumper as needed.
4. Reinstall the processor and power up.
5. Use programming software to write or restore the program to/from the EEPROM.

Selection Tips

• Select 32K capacity to match or exceed the processor’s user memory needs.
• Essential spare for critical PLC-5 program protection.
• Confirm processor series compatibility before installation.
