Product details

The Siemens 6AG1952-1AP00-7AA0 is a SIPLUS S7-400 MC RAM memory card providing 8 Mbyte of volatile program/data storage for S7-400 CPUs.

The card installs into any S7-400 CPU or interface module that accepts the standard long-format memory card. The altitude derating curve applies: at 2 000 m to 3 500 m, ambient temperature reduces by 10 K from the 70 °C maximum; from 3 500 m to 5 000 m, by 20 K. The card fits within the same panel cutout and slot width as the base part, no extra clearance needed for the conformal coating.

Frequently asked questions

What is the operating temperature range of this memory card?

It is rated from -25 °C to +70 °C, with altitude-based derating above 2 000 m.

How does this card compare to the standard 6ES7952-1AP00-0AA0?

The SIPLUS version shares the same 8 Mbyte RAM capacity and long form factor but adds conformal coating and wider temperature tolerance for use in harsh environments.
