Siemens 6ES7954-8LF03-0AA0 SIMATIC S7-1200/S7-1500 Memory Card 24MB PLC Memory Card

The Siemens SIMATIC S7 memory card (6ES7954-8LF03-0AA0) is a 3.3 V flash card with 24 MB capacity for SIMATIC S7-1x00 CPUs and SINAMICS drives, rated for a minimum of 500,000 write/delete cycles at 3 g card weight. Data retention after the final programming action is at least 10 years under normal use.

Technical Specifications

Selection Notes

Siemens lists this card as a spare part, so it is meant to replace a failed or lost memory card on an existing S7-1x00 CPU or SINAMICS drive rather than to spec a new build. 24 MB fits a mid-size S7-1200 or S7-1500 program plus recipe or data storage - check the target CPU's maximum supported card size before ordering. The 500,000-cycle minimum write/delete rating covers routine commissioning and program changes well beyond typical use.

Applications

Replacement load memory card for SIMATIC S7-1200 and S7-1500 CPUs, and for SINAMICS drives that use the same 3.3 V flash card format for program and parameter storage.
