Product Description:

The CX2900-0033 is a removable storage module produced by Beckhoff for the CX Embedded PC Systems series. It functions as a solid-state system drive that holds the operating system, PLC project files, and log data used by these DIN-rail industrial controllers. By matching the electrical and mechanical interface of the host CPU module, the card supports quick field replacement without shutting down the embedded PC. This role makes it the primary local storage device for boot files, retained application data, and routine operating records inside the controller.

Engineered to the Industrial card grade, the module uses the CFast form factor so it fits directly into the front slot of CX2000 processors. Inside, an array of SLC NAND elements provides single-level cell storage that favors longevity over density. The total provisioned capacity is 16 GB, which gives space for TwinCAT runtime, Windows IoT images, and user archives. Because the temperature range is classified as Extended, the card maintains read and write integrity when the controller is installed in panels that reach the higher limits common to factory floors. Data remains intact after power is removed, so the module does not depend on supercapacitors or batteries for retention.

The write endurance is graded as Increased, which means the media supports a higher program-erase count than consumer-grade flash before bit error thresholds are reached. When service does require a swap, the authorized spare is listed as the 8 GB CFast, and it can be prepared with the required image before installation. Because the media is inherently Non-volatile, the spare can be stored and transported without any energy source. This helps restore controller storage functions quickly when the original card must be removed from operation for inspection or replacement.
