Description
About the 6ES7952-1AP00-0AA0
About the 6ES7952-1AP00-0AA0
The Siemens SIMATIC S7 RAM memory card 6ES7952-1AP00-0AA0 is a volatile 8 Mbyte load memory module in the long-design form factor for SIMATIC S7-400 CPUs. It plugs into the CPU's card slot and depends on the CPU's battery backup to retain the user program when the rack is powered down, unlike the Flash-EPROM cards in the same family.
Selection Notes
Because this is a RAM card, the 8 Mbyte of user program data is held only as long as the CPU's backup battery is present and charged, so it needs the same battery-buffering discipline as the rest of the RAM series. Match the 8 Mbyte capacity to the load memory the target S7-400 CPU is specified for before ordering; a Flash-EPROM card is the non-volatile alternative in the same long-design form factor.
Applications
Load memory for SIMATIC S7-400 CPUs that take the long-design card format, used for initial program storage during commissioning or as a replacement for an existing S7-400 memory card.
