Product Description:

The 5ACPCI.RAIC-05 is a storage and RAID interface card manufactured by B&R Automation for the 5AC CNC Addon Modules series. Installed in a single PCI slot of a machine controller, the board carries two integrated 2.5-inch drives and a SATA controller so a CNC system can store machining programs, tool offsets, and process data locally without relying on an external server. By combining disk management and bus interfacing on one module, it streamlines data handling and backup in industrial automation cabinets where space and service access are limited.

The module reaches an average access time of 5.56 ms, which indicates how quickly stored blocks become available after a read request. Data moves through the SiI 3512 SATA link at a peak of 1.5 Gbit/s (150 MB/s), matching the Serial ATA 1.0 standard used on the host backplane. Each disk provides an onboard cache of 8 MB to hold frequently used sectors and reduce mechanical latency. Total installed capacity equals 250 GB, formatted into 512-byte sectors, and the physical platter turns at 5400 rpm, a speed that balances seek performance with vibration and power limits inside the control enclosure. The board enumerates two separate drives, giving the controller the option to mirror or stripe data across identical media while keeping sector addressing at 488,397,168 logical blocks.

For redundancy or throughput, the card supports RAID levels 0 and 1. The sustained path between the disks and the controller core is rated to 1175 Mbit/s, helping prevent the PCI bus from becoming a bottleneck during large program transfers. Draw on the backplane is limited to 0.3 A at 3.3 V, so thermal load inside the cabinet remains low, and only one conventional PCI slot is occupied. SMART monitoring tracks reallocated sectors, temperature, and spin-up counts during operation. Overall mass is 350 g, allowing the card to be seated securely in vibration-damped racks without additional mounting hardware.
