Product Description:

The CX5120-0123 Embedded PC from Beckhoff is part of a scalable controller series that supports compact and efficient control applications. It runs TwinCAT 2 NC I software which enables precise machine operations and integrates smoothly with industrial automation systems. The PC supports multiple operating systems, including Windows Embedded Standard 7 P, Windows Vista, for flexible deployment options.

The CX5120-0123 embedded PC features passive cooling through a fanless design that maintains system stability. The PC includes a CFast card slot with 1 MB of permanent memory and a microSD card slot for additional storage. An expansion interface with one free slot is available for additional connectivity. The PC can auto-detect I/O links for either E-bus or K-bus systems. The internal power system includes an integrated UPS that offers one-second power backup during power loss. The maximum power consumption for E-bus or K-bus is 11 W, and the current supply rating is 2 A. The unit includes LED indicators that show power status, TwinCAT activity, flash memory access, and bus state conditions. The PC is compliant with EMC requirements and holds CE and UL certifications. The clock is battery-powered and includes a replaceable battery.

The physical design of the CX5120-0123 PC measures 122 mm in width, 100 mm in height, and 92 mm in depth. The total weight is approximately 975 grams, which allows compact panel integration. The device includes an internal real-time clock that ensures time synchronization across systems. Shock and vibration resistance meet recognized industrial standards, which confirms mechanical stability. The embedded PC includes multiple LED indicators that enable fast diagnostics during operation. The PC supports applications in industrial automation that require reliability and compact performance.
