Product Description:

The CX2020-0122 is an embedded PC manufactured by Beckhoff within the CX Embedded PC Systems series. Serving as the central logic, motion, and visualization controller in compact machines, it integrates fieldbus interfaces and direct terminal connections so cabinet space is conserved. The platform uses an Intel Celeron 827E processor and operates under the TwinCAT 2 NC-PTP runtime, allowing PLC logic, axis interpolation, and soft-HMI tasks to run on a single DIN-rail device. Direct terminal connections also let the controller sit close to distributed I/O, which helps keep cabinet layouts compact and avoids the need for separate interface hardware.

Processing performance is delivered by a single CPU core running at 1.4 GHz, and that core is backed by 2 GB DDR3-RAM for code, variables, and real-time buffers. A non-volatile NOVRAM section of 128 kB secures retain data during sudden power loss, which helps preserve machine states and stored values during interruptions. Graphics are output through the DVI-I port at up to 1920 × 1200, allowing direct connection to widescreen operator panels. Network traffic is handled by 2 × RJ45 10/100/1000 Mbit/s adapters, while removable media, service tools, or barcode scanners connect over 4 × USB 2.0. The housing measures 144 × 99 × 91 mm and withstands 500 V dielectric tests between isolated groups, supporting safe installation in mixed-voltage cabinets.

The system’s electrical budget is capped at 21 W, drawing from a control supply of 24 V DC. Separate rail power for the attached I/O stations is limited to 2 A, which helps prevent excessive loading when many terminals are connected. An IP20 enclosure class guards against accidental contact but requires mounting inside a protective panel. Its modest heat output supports installation beside neighboring drives and power supplies when clear airflow paths are maintained inside the enclosure.
