SIEMENS 6ES7952-1AS00-0AA0 RAM Memory Card 16MB – SIMATIC S7-400 Series
Imagine a critical production line halting mid-shift because the PLC program memory fails to retain its configuration after a power cycle. Without a reliable RAM memory card, your S7-400 controller cannot store user programs, data blocks, or system parameters — leading to unplanned downtime, costly production losses, and emergency maintenance calls. The SIEMENS 6ES7952-1AS00-0AA0 RAM Memory Card eliminates this risk by providing stable, high-capacity volatile program storage directly within the CPU module slot.
The 6ES7952-1AS00-0AA0 is a 16 MB RAM Memory Card designed specifically for the SIMATIC S7-400 programmable logic controller platform — Siemens’ flagship high-performance PLC series for complex, process-critical automation tasks. Within the S7-400 memory card family, the 16 MB variant occupies the mid-to-high capacity tier, making it the preferred choice for large-scale programs, extensive data block structures, and multi-instance function block architectures. Globally, the S7-400 series remains one of the most widely deployed PLC platforms in heavy industry, and the 6ES7952-1AS00-0AA0 is a standard consumable component in long-running plant maintenance programs worldwide.

Frequently Asked Questions
Q: Is the 6ES7952-1AS00-0AA0 a RAM or Flash memory card?
A: It is a RAM (volatile) memory card. Program data is retained while the CPU is powered. For non-volatile backup storage, a separate Flash/EPROM card is required.
Q: Which S7-400 CPUs are compatible with this memory card?
A: The 6ES7952-1AS00-0AA0 is compatible with S7-400 CPU modules that feature a memory card slot. Please consult the Siemens S7-400 system manual or contact us to confirm compatibility with your specific CPU model.
Q: Can I use this card to back up my PLC program?
A: RAM cards store the active working program but are volatile — data is lost on power loss unless a battery backup (CPU-integrated) is present. For permanent program backup, use a Flash/EPROM memory card in conjunction with this RAM card.
Q: Do you supply new or refurbished units?
A: We supply both new (factory-sealed) and tested-good refurbished units depending on availability. The condition is clearly stated in the quotation. All units pass our QA inspection before shipment.
Q: What is the typical lead time?
A: In-stock items ship within 1–3 business days. For items requiring sourcing, lead time is typically 5–15 business days. Expedited options are available — contact us for details.
Q: Can you provide a certificate of origin or conformity?
A: Yes. We provide a certificate of conformity, commercial invoice, and packing list with every shipment. Additional documentation can be arranged upon request.
