5AC901.BX05-00
The 5AC901.BX05-00 Bus Unit from B & R Automation is a robust addon module in the 5AC CNC Addon Modules series, designed for high-precision industrial automation applications. Featuring 5 PCI half-size slots compliant with PCI standard 2.2, it delivers reliable data transfer at a 33 MHz bus speed for real-time CNC control and peripheral integration. The unit’s integrated fan cooling ensures sustained thermal management under continuous load, while its sturdy construction upholds a protection class of IP20. Engineered for ease of configuration, the 5AC901.BX05-00 supports both incremental and absolute encoder interfaces, enabling accurate motion feedback in demanding machining and robotics setups.
Technical specifications of the 5AC901.BX05-00 are comprehensive and tailored to industrial requirements. It operates on a rated input voltage of 3 x 400 – 480 VAC (±10%) at an input frequency of 50/60 Hz and provides a rated output voltage of DC 535 – 750 V with a rated output current of 5 A continuous. Maximum output power reaches 3.3 kW, and the switching stage functions within an 8 – 16 kHz switching frequency band for optimized motor drive performance. The module’s compact footprint of 72 mm × 322 mm × 219 mm and a weight of approx. 5.8 kg maximize cabinet space efficiency without compromising stability. Additional environmental resilience is afforded by its operating temperature range of 0 °C to +55 °C and Pollution Degree 2 classification under EN 61131-2.
Operational features underline the 5AC901.BX05-00’s capacity for continuous, precise control. A built-in PCIe to PCI bridge supports seamless integration of existing I/O and motion cards, while the five 32-bit slots accommodate diverse CNC addon cards. Encoder support for both incremental and absolute types guarantees high-resolution feedback critical to position control, minimizing deviation in high-speed machining. Vibration resistance up to 2 g and humidity tolerance from 5% to 95% (non-condensing) ensure dependable operation across a wide range of industrial conditions. The unit also performs reliably at altitudes up to 2000 m, making it suitable for global deployment.
System integration is streamlined within the B & R Automation ecosystem, allowing direct connection to ACOPOS, X20 I/O, and APC910 bus extensions for modular system expansion. Certification to CE, UKCA, and UL (cULus E115267) standards validates its compliance with international safety and performance regulations. The 5AC901.BX05-00 is optimally suited for CNC machine tools, automated assembly lines, packaging machinery, and robotic workstations where precise motion control and robust industrial endurance are paramount.
