Product Description:
The CX5020-0112 is an embedded PC produced by Beckhoff for the CX Embedded PC Systems series. This compact controller combines a low-power Intel architecture with modular I/O terminals to form a DIN-rail computer for machine control, data logging, and supervisory tasks in distributed automation. Its fanless housing allows the unit to operate as a central PLC, motion coordinator, or HMI server inside industrial control panels where standard office computers are unsuitable. The modular design also allows compatible terminals to be installed beside the controller without requiring separate field gateways or extensive interconnecting cables.
The device uses a single-core 1.6 GHz processor from the Intel Atom Z530 line, allowing deterministic execution of TwinCAT runtime threads without the thermal overhead of a larger CPU. Real-time field connections are implemented through the Beckhoff E-Bus backplane, which lets the controller operate EtherCAT or K-bus terminals directly. Plant networking is supported by two RJ45 ports with 10/100/1000 Mbit/s capability, enabling separate connections for control traffic and diagnostic communication. The front panel includes four USB 2.0 receptacles for touchscreens, storage devices, and other compatible peripherals. An Intel GMA 500 graphics core supports hardware H.264 decoding, reducing processor demand during camera or vision applications. The available interfaces support both local operation and communication with higher-level control systems.
Visual output is provided through a single DVI-D connector, allowing direct connection to digital displays with resolutions up to 1920 × 1200 pixels. Maximum heat generation remains below 12.5 W, which reduces the thermal load inside the control panel. The housing has an IP20 protection rating and is intended for installation inside switchgear that protects it from conductive dust and dripping liquids. Overall dimensions of 100 × 106 × 92 mm leave space on the DIN rail for terminal blocks and field wiring. A dielectric strength of 500 Veff separates the supply and logic circuits, supporting electrical isolation within the cabinet. The I/O supply has a current limit of 2 A, allowing the CPU module and a moderate terminal stack to operate from the available rail power.
