Product Description:

The 5A5001.02 is a hard disk module manufactured by B & R Automation and supplied within the 5A5 Hard Disks series. It provides rotating magnetic storage for controllers, operator terminals, and data acquisition units inside automated machinery. By keeping recipe data, parameter sets, and historical logs persistent during power cycles, the module supports reliable startup sequencing and traceability in industrial automation environments. The cartridge format allows quick exchange on the plant floor without specialized tools when capacity upgrades or planned replacements are needed.

With a compact form factor of 2.5 in, the disk fits drive bays that share the same footprint as portable computer media. Its carriage width is limited to 63.5 mm, so it aligns with standard rails inside B & R Automation panels. The carrier is classified as removable, meaning it can be slid out of its docking frame while the host electronics remain energized. A rubber mount isolates the housing from structural resonance, and the unit remains operational from 5 °C to 47 °C, covering the temperature range found in most control cabinets.

Data is stored on magnetic platters with a capacity of 1.44 GB, which is adequate for user programs, time-stamped logs, and firmware images used by contemporary PLC platforms. The medium is identified as a hard disk, so read-write access depends on spinning media that must withstand plant motion. Mechanical robustness is demonstrated by a shock tolerance of 150 G for 2 ms, protecting data when the enclosure experiences short-duration impacts. During continuous service, the spindle endures vibration levels up to 0.5 G, and this limit works with the rubber isolation to minimize track misalignment and maintain sector integrity under machine-induced oscillations.
