Features:
- Sixteen megabytes of Flash EPROM retain the stored load-memory contents without battery support.
- The long card design matches the defined SIMATIC S7-400 memory-card form.
- A 5 V card interface supplies the electronics during programming and CPU access.
The card holds persistent program and configuration content separately from the CPU work-memory area.
Flash technology permits the stored project to survive removal of operating power while remaining electrically programmable.
Correct selection depends on the required 16 MB capacity and the long S7-400 card format, not only on the 6ES7952 family prefix.
The Siemens 6ES7952-1KS00-0AA0 SIMATIC S7-400 16 MB Flash EPROM Memory Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Long-Format Memory Construction
- Card body: The long mechanical form aligns the connector and board with the designated S7-400 memory slot.
- Storage array: Flash EPROM cells hold 16 MB of load-memory data independently of the CPU's working RAM.
- Connector path: The card edge carries both the 5 V supply and the addressable memory signals through the CPU slot.
- Persistent content: Removal of controller power does not erase the programmed Flash EPROM image.
Project Storage and Transfer
- Load-memory role: Program blocks and configuration data reside on the card before the CPU copies required content for execution.
- Capacity check: The complete load-memory image must fit within the selected 16 MB card capacity.
- Power cycle: Stored project content remains present when the controller supply is switched off and restored.
- Slot match: The CPU must provide the S7-400 long-card interface rather than a different SIMATIC memory format.
Five-Volt Card-Slot Demand
- Supply source: The S7-400 card slot provides the 5 V operating supply directly to the memory electronics.
- Typical demand: Normal card access draws approximately 55 mA from the 5 V interface.
- Maximum demand: The documented current ceiling is 110 mA and belongs to the complete memory card.
- Retention state: Flash data remains stored even after slot power is removed.
Order-Code Details That Must Match
- Capacity code: The 1KS00 selection identifies the 16 MB storage class rather than a smaller S7-400 card.
- Memory medium: This order number specifies Flash EPROM, not a volatile RAM card.
- Mechanical form: Long design is part of the order configuration and must fit the target CPU slot.
- Complete suffix: The full 6ES7952-1KS00-0AA0 number distinguishes this exact card from adjacent capacities and forms.
