SIEMENS 6ES7954-8LL03-0AA0 New and Original High quality

6ES7954-8LL03-0AA0

The 6ES7954-8LL03-0AA0 memory card is an industrial grade Flash storage device designed specifically for the S7-1200/1500 series CPUs. It uses a 256MB Flash EPROM chip powered by 3.3V and has a minimum data retention capacity of 10 years and a minimum erase life of 200000 times. Its compact design (24mm × 32mm × 2.1mm) can seamlessly adapt to the storage expansion needs of the S7-1200 compact controller and the S7-1500 high-end PLC. By supporting program firmware upgrades, recipe data backup, and system image storage functions, it effectively ensures the rapid recovery ability of the production line in the event of power outages or failures. At the same time, it complies with RoHS directive environmentally friendly materials and IP67 protection standards, making it suitable for high temperature, high humidity, and strong electromagnetic interference. The ability to maintain stable operation in industrial field environments is the core component for Siemens PLC systems to achieve intelligent upgrades and secure storage of production data.
