Long-format 4 MB RAM memory card for S7-400 CPUs
Siemens 6ES7952-1AM00-0AA0 is a SIMATIC S7 RAM memory card for compatible S7-400 controllers. The official technical data sheet identifies a long-format card with 4 Mbytes of RAM capacity and an approximate weight of 55 g. It is used to provide working memory for programs and data in supported S7-400 CPU configurations. Because RAM contents depend on the controller power and backup concept, replacement planning should include a verified project backup. Before procurement, check the full suffix, CPU type, required memory capacity, card format, battery condition, power-down procedure and software restoration plan.

It identifies a long-format SIMATIC S7-400 RAM memory card with 4 Mbytes capacity.
The official Siemens data sheet specifies RAM memory.
The documented memory capacity is 4 Mbytes.
No. CPU compatibility, memory type, capacity and mechanical format must be matched.
Verify the CPU, project backup, battery condition, shutdown procedure and restoration plan.
Yes. Request label, contact, full-card and packaging photographs before shipment.

Structured evidence, practical engineering checks and worldwide shipment coordination
Industrial automation spares are often selected under tight maintenance schedules, where an incorrect suffix, connector or hardware revision can delay commissioning. Our team reviews the buyer’s complete order code, visible nameplate, connector arrangement, housing condition and requested accessories before dispatch. For SIMATIC memory cards, we also encourage checks covering CPU compatibility, RAM capacity, card format, battery condition, contact cleanliness, project backup and the planned controller shutdown and restoration procedure.
The following photographs show real Stockoems working environments and demonstrate how our team handles technical review, documentation checks and logistics preparation.
| Review Area | Stockoems Support |
| Identity Verification | Complete order code, suffix and readable label evidence |
| Visible Condition | Housing, connectors, seals, terminals and accessory review |
| Configuration Questions | Buyer-provided network, power, interface and installation details |
| Documentation | Clear photographs and packing evidence for approval |
| Packaging | Protective materials selected for industrial electronic equipment |
| Shipping Coordination | Destination, carrier options and export packing requirements |
After receiving the requested part number, quantity, destination and installed-unit photos, our team organizes the review scope. Available-unit photographs can cover the full enclosure, readable label, connector faces, accessories, seals and packaging. Any compatibility decision remains with the buyer’s engineering team, while Stockoems provides clear commercial evidence and procurement support to make that decision easier.
