Description

The Siemens 6ES5373-0AA41 is a non-volatile C-EPROM memory submodule designed for use with the legacy SIMATIC S5 programmable logic controller (PLC) systems. This module provides reliable, permanent storage for user programs and system configurations, ensuring that critical automation logic remains intact even in the event of a total power loss or control system battery failure.

Features

• 32 Kbytes storage capacity for robust program retention.
• Non-volatile CMOS EPROM technology eliminates the need for backup power or batteries to maintain data.
• Designed for seamless integration into the dedicated memory expansion slot of S5 series CPUs.
• Gold-plated edge connectors ensure stable electrical connectivity in high-vibration industrial environments.
• Compact, durable form factor suitable for legacy control cabinet architectures.

Applications

This memory submodule is widely utilized in legacy industrial automation sectors, including power generation, heavy manufacturing, and material processing facilities. It is an essential component for engineers maintaining older SIMATIC S5 infrastructure who require a secure, hardware-based method for program storage and rapid system recovery.

Technical Specifications

Installation Guidelines

• Ensure the S5 CPU is powered down before inserting or removing the memory submodule to prevent electrical damage or data corruption.
• Handle the module by the edges to avoid electrostatic discharge (ESD) damage to the internal integrated circuits.
• Align the module carefully with the CPU memory slot guide rails and press firmly until the edge connector is fully seated.
• Verify that the module is properly locked into place if the specific CPU housing includes a locking mechanism.
• Keep the module away from high-EMI sources and extreme moisture to maintain long-term data integrity.
