The Siemens 6ES7952-1KT00-0AA0 is a SIMATIC memory card for the S7-400 CPU family, built as a long-design 5V Flash-EPROM card with 32 Mbyte capacity. It plugs into the S7-400 CPU's memory card slot to hold the user program, block data and configuration. At 53 g, it is a field-swappable card for loading a program onto a new CPU or transferring it between S7-400 stations.
This 32 Mbyte card sits between the smaller and larger long-design S7-400 cards: pick it over the 16 Mbyte version when the program plus retentive data no longer fits with headroom, and step up to the 64 Mbyte card instead if future expansion of the program or recipe data is planned.
