The Siemens SIMATIC S7 Memory Card 6ES7 952‑0KH00‑0AA0 is a Flash EPROM memory module designed specifically for use with SIMATIC S7‑400 series PLCs to expand and retain critical program and configuration data.
Built with a 256 KB Flash EPROM memory architecture, this card provides reliable non‑volatile storage of user programs, system parameters, and engineering configurations, ensuring that key automation logic and settings are preserved even when the PLC powering down or during maintenance operations.
Engineered for industrial automation environments, the 6ES7 952‑0KH00‑0AA0 card plugs directly into the memory slot of compatible S7‑400 CPUs and serves as the primary load memory or program backup medium for systems lacking internal storage or requiring additional capacity.
Its long‑form factor and standardized interface ensure seamless integration with existing PLC racks and modules, and its Flash technology supports multiple read/write cycles while maintaining data integrity under typical factory conditions.
