Siemens 6ES7952-1KY00-0AA0 SIMATIC S7-400 Memory Card 64 MB Flash-EPROM PLC Memory Card

The Siemens 6ES7952-1KY00-0AA0 is a SIMATIC memory card for the S7-400 CPU family, built as a long-design 5V Flash-EPROM card with 64 Mbyte capacity. It plugs into the S7-400 CPU's memory card slot to hold the user program, block data and configuration. At 54 g, it is a field-swappable card for loading a program onto a new CPU or transferring it between S7-400 stations.

Selection Notes

This is the largest-capacity card in the long-design S7-400 line-up covered here, suited to CPUs running large programs, extensive DB data or block libraries that outgrow the 16 Mbyte and 32 Mbyte cards. Where the program is small, the lower-capacity cards cost less without any functional difference.
