CB2051-0005
by Beckhoff
The Beckhoff CB2051-0005 industrial motherboard from the CB Modular Motherboards series delivers a high-performance, field-proven computing platform for demanding automation and control environments. Designed and manufactured by Beckhoff, the CB2051-0005 supports Intel® Celeron® M, Core™ Duo, and Core™2 Duo processors on an Intel® 945GM and Intel® ICH7 chipset foundation for stable, embedded operation. With a compact PISA-Slot, 192 mm x 125.5 mm form factor, this board seamlessly integrates into PISA expansion systems, providing reliable processing power in a rugged footprint. Critical interfaces include up to 2 GB of DDR2-667 RAM across two SO-DIMM200 slots, dual Ethernet LAN ports, multiple serial COM ports, and comprehensive USB connectivity for flexible I/O configurations.
At the heart of the CB2051-0005 lies an AWARD BIOS 6.10 firmware environment, ensuring straightforward configuration and boot management. Memory support is rated at DDR2-667 with a memory capacity of up to 2 GByte via two SO-DIMM200 slots, while storage interfaces include two SATA channels and a legacy IDE interface available for backward compatibility. Network connectivity is furnished by LAN Port 1: Ethernet 10/100 Base-T and LAN Port 2: Ethernet 10/100/1000 Base-T, and there are eight USB 2.0 interfaces to attach peripheral devices. User expandability is enhanced through one MiniPCI slot and a full PCI bus accessible through the PISA connector. GPIO demands are met by 16x GPIO lines, and audio output leverages AC97 compatibility with SPDIF for digital sound environments.
Operational performance is engineered for continuous uptime in industrial settings, featuring support for extended temperature ranges and shock/vibration resistance inherent to PISA-based designs. The board's four serial COM ports (COM1 to COM4) offer straightforward RS-232/RS-485 integration for legacy instrumentation and sensor networks. Display outputs are versatile, with both CRT and LVDS interfaces available for local HMI installations or flat-panel integration. Power management and system health monitoring functions are exposed via the BIOS and GPIO channels, enabling real-time diagnostics and remote maintenance. The combined USB, LAN, and serial interfaces support simultaneous communication tasks without compromise, ensuring deterministic I/O timing for automation cycles.
System integration is simplified by adherence to standard PISA-Slot specifications, enabling drop-in replacement or expansion alongside other Beckhoff modules. The CB2051-0005's compatibility with mainstream Intel processor families makes firmware updates and software deployment consistent across multiple platforms. Target applications include factory automation controllers, machine vision systems, process monitoring terminals, and embedded SCADA nodes where reliability and low-latency I/O are essential. Its broad feature set and ruggedized design make the CB2051-0005 an ideal core component for complex industrial automation infrastructures.
