Product Description:

The 5CFCRD.0512-03 CompactFlash card is manufactured by B&R Automation as part of the 5CF Compact Flash Cards series. The device supplies non-volatile mass storage to automation controllers, human-machine interfaces, and drive-based CPUs. Within these systems it stores application files, parameter sets, and event logs, allowing software to be replaced or updated without specialized tools. Because factory floors induce vibration and thermal cycling, the card relies on solid-state memory rather than rotating media, reducing mechanical failure points and shortening restart times after service.

Its storage capacity of 512 MB offers enough space for control logic, event archives, and boot images common to B&R X20 and X90 platforms. The memory uses SLC flash, so each cell stores a single bit, resulting in faster cell access and higher endurance than MLC media. Typical sustained read throughput is 8 MB/s, permitting rapid controller start-up, while write performance reaches 6 MB/s for quick recipe updates. To distribute physical wear across the array, the card uses static wear leveling, and unchanged sectors are periodically relocated to extend service life. Built-in ECC continuously checks and corrects bit errors during every transfer. The card measures 42.8 mm wide, 36.4 mm long, and 3.3 mm high, so it fits standard Type I CompactFlash sockets without mechanical adapters.

The error rate is limited to <1 per 10^14 bits read, which matches the reliability targets for safety-related logs. Endurance is specified at >2,000,000 cycles of block erase and rewrite, allowing frequent recipe changes over years of shift operation. Under a 25 °C reference, the mean time between failures exceeds >4,000,000 h, which helps reduce unexpected interruptions in continuous-run production lines. The card weighs only 11.4 g, keeping mass low for vibration-isolated CPU carriers. Its housing is sealed against dust, and the tight dimensional tolerances help maintain firm insertion force even after numerous removals.
