Description
About the 6ES7952-1KL00-0AA0
About the 6ES7952-1KL00-0AA0
The Siemens SIMATIC S7 memory card 6ES7952-1KL00-0AA0 is a 5V Flash-EPROM load memory module in the long-design form factor for SIMATIC S7-400 CPUs, storing 2 Mbyte of non-volatile user program data. It plugs into the CPU's card slot and retains its contents without battery backup, unlike the RAM cards in the same family.
Selection Notes
Because this is a Flash-EPROM card, the 2 Mbyte of user program data survives a power-down without the CPU battery, which makes it the safer pick over an equivalent-size RAM card for programs that must not be lost on a dead or missing battery. Match the 2 Mbyte capacity to the load memory the target S7-400 CPU is specified for before ordering.
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.
