Standard consumer-grade CompactFlash cards are not built to survive inside a sealed industrial panel PC, where temperatures can swing from a cold winter shutdown to a mid-summer heat load. The 6AV6574-2AC00-2AA1 is a factory‑qualified 512 MB CF card specifically released for SIMATIC HMI and Panel PC applications. It stores embedded operating systems, project files, and log data with a level of endurance and data integrity that a generic office‑supply card cannot match.

Industrial Reliability

• Wide‑temperature operation: rated for continuous use from -25 °C to +70 °C, covering the full thermal range of a non‑ventilated operator panel enclosure.
• 2 million hours MTBF: the card is verified for 24/7 operation, reducing unplanned downtime caused by storage failure in critical HMI stations.
• 10‑year data retention: even if the panel is powered off and stored for extended periods, the stored program and configuration remain intact and bootable.

Backup & Recovery in One Piece

• Use the 512 MB capacity to clone the entire system image of a Windows‑embedded HMI or to store a long‑term data archive.
• In the event of a hardware fault, simply move the CF card to the replacement unit and restore full operation without reloading software or re‑entering parameters.

Physical Specifications

• Dimensions: standard CompactFlash Type I housing, supplied with a plastic carrier tray that simplifies insertion into the target device.
• Weight: approx. 15 g including the carrier tray.
