Product Description:

The 5AC902.BX02-00 is a CNC add-on card manufactured by B&R Automation and assigned to the 5AC CNC Addon Modules series. Installed beside the primary CPU of a machine control PC, the board supplements motion logic so that additional interpolated axes, high-speed I/O tasks, and diagnostic channels can be processed deterministically. By plugging directly into the system backplane, it expands numerical-control capacity without requiring a complete controller replacement. It is intended for control platforms that need more motion resources while keeping the existing hardware layout and software environment in place.

Signal exchange with the host takes place over a parallel bus clocked at 33 MHz, a frequency suited to deterministic motion loops and time-sensitive control data. Data move across a 32-bit pathway, allowing the module to transfer full double-word parameters in one bus cycle for efficient communication with the host system. Mechanical form follows the PCI half-size format, so the card fits compact industrial PCs with limited board length. Electrical compliance with the PCI 2.2 standard keeps bus timing and voltage behavior compatible with conventional hardware platforms. The populated components stop at a depth of 75 mm, which helps maintain clearance for internal cabling and airflow in short 19-inch enclosures.

The front edge of the board spans 164 mm while its tallest component reaches 218 mm, a profile suited to rack-mount chassis that use vertical card orientation. An integrated PCIe-to-PCI bridge allows the card to operate in systems that provide PCIe lanes rather than a native PCI slot. Storage expansion is supported by 1 slide-in drive bay on the carrier, and peripheral cards can be installed in 2 internal module slots without external cabling. This arrangement keeps additional interface hardware contained within the PC housing and helps preserve clear internal cable routing.
