Product Description:

The CX5120-0141 is an embedded PC manufactured by Beckhoff for the CX Embedded PC Systems series. It serves as a DIN-rail control platform that combines processing, memory, and fieldbus connections in a compact housing. The unit can host PLC logic, motion tasks, and operator interfaces inside switchgear cabinets where available space and power are limited.

Processing is handled by an Intel Atom E3815 1.46 GHz CPU with a single-core architecture, providing deterministic single-thread execution for time-critical sequences. The controller carries 2 GB of DDR3 RAM for the real-time operating system, user programs, and process data, while 256 MB of dedicated graphics memory supports local HMI rendering. Its compact housing measures 122 × 100 × 92 mm, enabling dense cabinet layouts or direct mounting beside I/O terminals. Typical operation requires only 11 W, which simplifies power-supply sizing and limits heat buildup inside the enclosure. An internal 10 W bus power budget is available for attached Beckhoff I/O slices, reducing the need for external feed modules.

The unit accepts a regulated 24 V DC supply and withstands up to 500 V of dielectric stress between isolated circuits, improving reliability in electrically noisy industrial environments. For display connectivity, the DVI-I port supports resolutions up to 1920 × 1200, allowing compatible high-resolution panels to connect without additional converters. Four front-mounted interfaces provide four USB 2.0 ports for service tools, storage devices, or touchscreens, with each port supporting up to 500 mA. The system also supports an uninterruptible power supply module that increases total power consumption to 18 W. Its one-second energy buffer allows the file system to close safely after a loss of incoming power, helping prevent data corruption during an unexpected shutdown.
