Siemens 6ES7954-8LL03-0AA0 SIMATIC S7 256MB Memory Card for S7-1200/S7-1500 CPU 3.3V Flash

The 6ES7954-8LL03-0AA0 is a Siemens SIMATIC memory card with 256 MB Flash-EPROM memory and a 3.3 V operating specification. It is intended for use with Siemens S7-1x00 CPU systems and provides non-volatile storage for PLC programs, configuration information and other CPU-related data.

The memory technology provides a minimum specified 200,000 write/delete operations. Siemens specifies data retention of at least 10 years when the number of write/delete operations remains below 20,000, while retention is specified at approximately 1 year under extremely high write/delete usage above 180,000 operations.

Important for DYYCloud: this is a memory card/accessory, not a PLC CPU, I/O module or general-purpose SD card. Compatibility with the target CPU should be checked before ordering.
