That coating is the difference between a card that survives in a climate-controlled electrical room and one that holds the unit on the grid in a turbine hall where the ambient climbs past 50 °C. ## Memory sizing and compatibility 64 MB of RAM, no flash retention on power loss — this is a load-memory card for the S7-400 rack, not a permanent program store. The CPU loads the user program and data blocks from this card into its internal RAM at startup; on power cycle the card contents are lost unless the program is also held on the CPU's own memory card or an EPROM card. Belongs to the S7-400 product family, so it fits the long-design memory-card slot on any S7-400 CPU or CP that accepts the standard RAM card format. The 64 MB capacity is sufficient for mid-range S7-400 applications — a large recipe database or a multi-axis motion program will push against that ceiling, and you would step up to the 128 MB or 256 MB variants if the project calls for it. ## Environmental and altitude derating The -25 °C to +70 °C range is the full operating envelope at sea level. At altitude the upper limit derates: above 2 000 m the maximum allowed temperature drops by 10 K per 1 500 m increment, so at 3 500 m the card is good to 60 °C, and at 5 000 m it is good to 50 °C. The lower limit stays at -25 °C across the full altitude range. The conformal coating also qualifies the card for ANSI/ISA-71.04 GX group A/B environments — hydrogen sulfide, chlorine, and other corrosive gases up to EN 60721-3-3 class 3C4 limits — plus salt spray and oil exposure. That makes it a candidate for offshore platforms, chemical plants, and paper mills where the standard card would fail from creep corrosion inside two years.","metaTitle":"Siemens 6AG1952-1AY00-7AA0 SIPLUS S7-400 RAM 64 MB","metaDescription":"SIPLUS S7-400 MC RAM 64 MB based on 6ES7952-1AY00-0AA0 with conformal coating, -25 to +70 °C.
