Siemens 6es79548le040aa0 Memory Card 12 Mb

Product Description

The SIEMENS 6es79548le040aa0 is a 3.3-volt flash memory card designed for use with Simatic S7-1x00 CPU and SINAMICS drive systems. With a 12 MB storage capacity, this card provides non-volatile program and data storage directly on the controller, eliminating the need for a separate memory module or battery-backed RAM in supported configurations. It is installed by automation technicians and controls engineers working on programmable logic controller (PLC) systems in industrial and commercial environments.

This memory card is used in Simatic S7-1x00 CPU applications and compatible SINAMICS drive platforms. Typical installations include industrial automation panels, machine control systems, and variable frequency drive configurations where persistent program storage is required. The card slots directly into the supported CPU or drive unit and is recognized automatically by the controller upon insertion.
