Description
Siemens 6ES7954-8LF03-0AA0
SIMATIC S7 Memory Card | 24 MB Flash-EPROM | 3.3 V | S7-1200 / S7-1500 CPU and SINAMICS Compatibility
Product Detailed Description
The Siemens 6ES7954-8LF03-0AA0 is a 24 MB SIMATIC Memory Card designed for Siemens S7-1×00 PLC CPUs and compatible SINAMICS drive systems. It uses 3.3 V Flash-EPROM technology to store user programs, configuration data, and other system information required by supported automation devices.The card provides a memory capacity of 24 MB and supports a minimum of 500,000 write/erase operations. Siemens specifies a minimum data retention period of 10 years under defined usage conditions. Its compact design allows installation in compatible SIMATIC controllers and drive systems. This memory card is a dedicated Siemens SIMATIC storage accessory rather than a generic SD card. It must be used with supported Siemens hardware and the appropriate system configuration.
