1785-ME32 Allen-Bradley Non-Volatile User Program Storage Module

Product Description

The Allen-Bradley 1785-ME32 functions as a non-volatile EEPROM (Electrically Erasable Programmable Read-Only Memory) storage solution for the PLC-5 controller platform. This module provides 32 kilobytes of dedicated memory space, primarily serving to safeguard user programs, device configurations, and critical calibration tables against power loss. By utilizing this expansion module, system integrators ensure that vital automation logic remains intact within the processor’s memory architecture even during extended downtime or battery failure.

Technical Specifications

The 1785-ME32 features a specialized interface for direct integration into PLC-5 processors, offering robust protection against industrial electrical noise.

Operational Features

• Advanced Data Redundancy: The module acts as a secure backup for the processor’s RAM. Consequently, the system can automatically reload the control logic upon power restoration, which eliminates the need for manual intervention or external PC downloads.
• Extended I/O Support: This memory hardware supports configurations involving up to 3072 analog I/O points and coordinates communication for up to 32 remote I/O chassis per link. These capabilities allow the module to manage data-heavy architectures in large-scale manufacturing plants.
• High-Durability Design: Engineered for harsh environments, the 1785-ME32 withstands significant physical impact and high-frequency electromagnetic interference. The module continues to operate reliably in non-condensing humidity levels reaching up to 95%.
• Reprogrammable Logic: Unlike standard ROM, this EEPROM module allows users to overwrite stored data multiple times using higher voltage pulses. This flexibility enables technicians to update system firmware or logic tables as production requirements evolve.
• Integrated Expansion Port: The unit includes a Control Coprocessor expansion port. This interface facilitates seamless communication between the memory module and auxiliary processing hardware, enhancing the total throughput of the PLC-5 system.
• 100% Brand New Condition: We provide only original, factory-sealed Allen-Bradley modules to ensure maximum reliability. Choosing new components prevents the data corruption risks often associated with aged or refurbished memory chips.
