Product Description:
The CB1051-0003 is a modular industrial motherboard produced by Beckhoff within the CB Modular Motherboards series. In an automation controller or embedded PC, this board forms the central computing layer, hosting the processor, memory, and field-interface controllers needed for motion, logic, and visualization tasks. By concentrating standard PC functionality on a compact industrial form factor, it lets machine builders integrate Beckhoff TwinCAT runtime or other real-time operating systems directly on the shop floor.
The board uses the Intel 945GM(E) northbridge and ICH7R southbridge, identified collectively as Intel 945GM(E), ICH7R; this chipset supplies the memory controller hub, PCI Express root complex, and SATA/PATA I/O logic. A processor is seated in the mPGA479M socket, enabling installation of mobile Intel Core processors while keeping thermal load low for fanless enclosures. Card expansion is possible through 3 x PCI, 3 x PCIe x1, 1 x PCIe x16, so fieldbus masters or GPU accelerators can be added without a backplane. Mass-storage media connect to the board over 4 x SATA channels, and RAID modes provided by the chipset allow mirroring or striping of drive data. For peripheral attachment, there are 8 x USB 2.0 ports that support cameras, HMI panels, or service keys at 480 Mbit/s each. The AWARD BIOS 6.10 handles power-on self-test and offers watchdog and PXE network boot settings required in headless control cabinets.
Up to 4 GB of system memory can be installed in two DIMM240 slots, and the board supports this capacity at the rated DDR2-667 speed on 1.8 V modules. Physical dimensions of 305 x 220 mm follow the Beckhoff CB form factor, simplifying direct mounting on DIN-rail carrier plates. Integrated graphics is handled by the Intel 945GME core, while dual Ethernet controllers provide one Fast Ethernet port and one Gigabit port for soft PLC, OPC UA, or EtherCAT communication. A Realtek ALC655 codec offers line-level audio for annunciation. Legacy needs are met with four COM serial ports and a single PATA connector for optical drives or older solid-state disks, allowing backward-compatible upgrades of existing machines.
