Product Description:

The CX2020-0112 is an embedded PC module produced by Beckhoff within the CX Embedded PC Systems series. Intended for DIN-rail installation at machine level, the unit combines PLC, motion control, and HMI tasks so that distributed I/O can be supervised directly on the factory floor. By running Beckhoff’s automation runtime, the device acts as a central controller for production cells, handling deterministic communication to fieldbus terminals and Ethernet-based networks while occupying only a small footprint inside the electrical cabinet and reducing the need for a separate industrial PC in compact control layouts.

The computing section is built around an Intel Celeron 827E processor clocked at 1.4 GHz; with just one core, deterministic scheduling of real-time tasks remains predictable and easy to validate. A 2 GB DDR3 RAM module stores the operating code and buffers process variables exchanged by the TwinCAT 2 NC-PTP Runtime, while instruction-persistent data are retained in a 32-bit memory map. Under full load, the module draws up to 21 W, and it accepts a control-cabinet supply between 20.4 and 28.8 V, specified as 24 V DC (-15 %/+20 %). The modest thermal envelope lets the fanless housing dissipate heat passively, maintaining deterministic operation without moving parts.

For nonvolatile diagnostics, it carries 128 kB of NOVRAM that logs power-fail events without battery support. Two Gigabit Ethernet channels provided through 2 × RJ45, 10/100/1000 Mbit/s sockets allow machine-to-machine messaging and programming from supervisory PCs. Four high-speed USB host ports, listed as 4 × USB 2.0, can supply up to 500 mA each, enabling barcode scanners or service drives to be connected without external hubs. The housing meets the IP20 protection class, measures 144 mm wide, 99 mm high, and 91 mm deep, and clips directly onto a DIN rail alongside I/O slices so that control logic, communication links, and local terminals occupy a continuous assembly with short interconnections.
