Siemens 6ES79538LG300AA0 Flash Memory Card

Product Description

The SIEMENS 6ES79538LG300AA0 is an industrial flash memory card designed for use with Siemens programmable logic controllers and automation systems. It provides non-volatile program and data storage, allowing control programs, configuration data, and project files to be saved, transferred, and retained without battery backup. Licensed automation technicians and industrial controls specialists install this card as part of PLC commissioning, firmware updates, or program backup procedures in manufacturing, process control, and building automation environments.

This flash memory card is suited for industrial control applications where reliable, non-volatile storage is required. It is typically installed in Siemens S7-series or compatible PLC CPU slots during initial system setup or when transferring control programs between controllers. Its compact form factor and solid-state design make it appropriate for panel-mount and cabinet-mount installations where space and vibration resistance are considerations.

Key Features

• Non-volatile flash storage retains program and data without battery backup
• Compact card form factor fits dedicated memory card slots on compatible PLC CPUs
• Supports program transfer, firmware updates, and project archiving
• Solid-state design with no moving parts for reliable operation in industrial environments
• Lightweight at 0.066 pounds for easy handling during installation

Compatibility

Designed as an OEM-style replacement or spare memory card for compatible Siemens industrial PLC and automation controller platforms that accept this card format.

Installation Notes

Installation should be performed by a qualified controls technician or automation specialist familiar with Siemens PLC systems. Always power down the controller before inserting or removing the memory card unless the specific CPU documentation explicitly permits hot-swap operation. Follow the controller manufacturer's documentation for proper program load and transfer procedures to avoid data loss or controller faults. Handle the card by its edges to avoid electrostatic discharge damage to internal flash memory components.
