SIEMENS SIMATIC S7 Memory Card, 256 MB Bangladesh. Mlfb -6ES7954-8LL04-0AA0 price

The Siemens 6ES7954-8LL04-0AA0 is a SIMATIC S7 Memory Card with 256 MB capacity for compatible S7-1x00 CPU applications. The card uses 3 V Flash-EPROM technology and is part of Siemens' SIMATIC S7 memory-card range. It provides removable storage for supported controller applications and has a specified minimum endurance of 200,000 write/delete operations. Siemens documentation specifies data retention of at least 10 years under the stated usage conditions, with the retention period dependent on cumulative write/delete activity. The physical dimensions are 24 mm × 32 mm × 2.1 mm, with an approximate weight of 3 g. Siemens lists the 256 MB card among the standard memory-card capacities used with supported S7 controller families.
