Product Description:
The CX5120-0162 embedded PC is produced by Beckhoff for the CX Embedded PC Systems series. It mounts on a DIN rail inside a control cabinet and combines PLC, motion, and HMI duties in one housing. Acting as the central controller, the unit exchanges fieldbus data, executes deterministic logic, and hosts visualization tasks without requiring a separate rack PC. This arrangement allows local control and display functions to run in the same unit as the machine logic, which reduces panel complexity and shortens internal wiring paths. An integrated system bus lets it drive EtherCAT terminals, making it suitable for small to mid-size machines that need real-time coordination of axes and process I/O.
It includes an Intel Atom E3815 processor running at 1.46 GHz, and the single-core architecture keeps thermal load low while allowing the TwinCAT 2 NC PTP Runtime to execute motion sequences with millisecond accuracy. The CPU is backed by 2 GB DDR3-RAM and a shared 256 MB graphics buffer that store code, variables, and the lightweight Windows display driver. Two Gigabit Ethernet ports presented as 2 × RJ45, 10/100/1000 Mbit/s link plant networks, while a 24 V DC supply powers the logic stage. Network separation can be used for machine communication on one port and service access on the other, depending on the control architecture. Four USB 2.0 connectors rated at 500 mA each accept scanners or service sticks, and the controller provides 10 W on the E-bus or K-bus backplane for distributed terminals. A one-second UPS capacitor bridges brief voltage dips so file systems can close correctly.
At full load, the controller draws only 11 W, which helps limit heat buildup in compact cabinets. Insulation between logic and field levels withstands 500 V, and the housing carries an IP20 rating for protected indoor installation. Its profile of 122 × 100 × 92 mm leaves DIN-rail space for additional I/O slices, and the narrow enclosure fits well in modular control layouts. The low power draw reduces cabinet heat, while the compact housing preserves room for adjacent terminals and power components.
