SIMATIC S7-300 4MB Flash EPROM Memory Card

The SIMATIC S7-300 4MB Flash EPROM memory card is a vital Siemens S7-300 series programmable logic controllers (PLCs) accessory. Designed in a compact, short format, this memory card offers 4 megabytes of reliable, non-volatile memory storage, ideal for use in demanding industrial automation environments. The 5V Flash EPROM technology ensures that data written to the card is retained even during power loss. It securely stores user programs, configuration data, and operating system updates for Siemens S7-300 CPUs. Built specifically for compatibility with Siemens systems, this memory module seamlessly integrates with the SIMATIC architecture to support fast, dependable data storage and retrieval.

Reliable Storage for Industrial Automation

This memory card plays a critical role in PLC performance by providing permanent storage for user programs and machine-specific configuration data. The 4MB capacity offers ample space for large and complex control applications. Unlike volatile memory that loses data when power is interrupted, the Flash EPROM ensures all essential programming is preserved, reducing system recovery time and preventing costly downtime. Whether used in machine control, process automation, or building management systems, the card provides the reliability and durability needed in industrial applications.

Compact Design with Maximum Compatibility

This memory card's short design form factor makes it ideal for installations with limited panel space. It fits directly into the memory card slot of Siemens S7-300 CPUs without requiring additional components or adapters. The 5V operating standard ensures optimal performance and energy efficiency, and its rugged construction is engineered to endure the vibration, temperature, and electrical noise often encountered in automation environments. As part of the SIMATIC family, this card supports smooth interoperability with Siemens hardware and software tools.

Enhanced System Functionality and Maintenance

A 4MB Flash EPROM memory card enables advanced functionality in S7-300 systems. It allows for the easy transfer of programs between devices, firmware updates, and backup creation. During system commissioning or maintenance, technicians can quickly swap out the card to update configurations or replace controllers without connecting a PC or downloading files manually. This convenience speeds up installation and minimizes equipment downtime, making it a practical tool for system integrators and maintenance teams.
