Product Description:
The CB1050-0003 modular motherboard is produced by Beckhoff within the CB Modular Motherboards series. It functions as the central computing layer inside industrial PCs and compact controllers, hosting automation software that coordinates motion, I/O, and human-machine interfaces. By conforming to the ATX layout, it can be installed in standard control cabinets and supports PC-based control platforms with familiar mechanical and electrical provisions. Its component selection is intended for long-term availability in machinery and process applications that remain in service for extended operating periods.
It is built around the Intel 855GME + ICH4 chipset, so it supports Celeron M or Pentium M processors with a 400 MHz front-side bus, balancing thermal load with predictable cycle times. Two DIMM-184 sockets accept DDR-333 modules up to 2 GB, and the board addresses that memory at 333 MT/s for steady data access during cyclic control tasks. System expansion is available through 6 PCI slots, which allows add-in cards for fieldbus, motion, or communication functions when the application requires them. The 20-pin ATX + 4-pin 12 V power connection supplies both logic and auxiliary rails, while dual IDE channels and the LVDS display interface support storage devices and flat-panel output.
A 1 × AGP 4× edge connector permits a discrete graphics card for applications that need expanded visualization capability or multiple display outputs. Legacy equipment can still attach through the four serial ports, while peripherals connect through the six USB 2.0 ports for removable media, input devices, and service access. The board’s 305 × 220 mm footprint aligns with mounting holes in standard ATX chassis, which helps it fit established enclosure layouts without unusual brackets or carrier plates. The layout also leaves space beside the board for passive backplanes or DIN-rail power supplies in deeper enclosures, which can simplify internal placement when several control components share one cabinet.
