Product Description:

The CX5020-1121 embedded PC is produced by Beckhoff within the CX Embedded PC Systems series. As a DIN-rail-mounted controller, it combines PC performance with PLC functions to coordinate motion, I/O, and visualization tasks in industrial automation cells. The unit provides a compact central processor that interfaces directly with Beckhoff’s modular I/O terminals, allowing machine builders to deploy deterministic control logic without a separate rack-mounted computer. It is intended for decentralized cabinet installation on production lines and in process plants.

Its processing core runs at 1.6 GHz, a clock frequency delivered by the Intel Atom Z530 processor, so deterministic task cycles can be scheduled while maintaining low thermal dissipation. The control electronics operate from a 24 V DC supply commonly used in control cabinets. Dual-port Gigabit networking is available through 2 × RJ45 connectors that support 10/100/1000 Mbit/s connections to drives, HMIs, or higher-level SCADA systems. The unit also has four USB 2.0 host ports for data drives, keyboards, or fieldbus adapters. Each USB port supplies 500 mA in accordance with the USB standard, supporting data logging and peripheral connections without extra hubs.

The housing measures 100 × 106 × 92 mm, carries the series’ K-bus interface for terminal expansion, and includes five status LEDs that indicate the run state, bus activity, and system errors. The enclosure has an IP20 rating, while the internal components dissipate no more than 12.5 W, reducing panel cooling demands. Galvanic isolation between the power supply and logic withstands 500 V RMS. The backplane can supply up to 2 A to attached I/O terminals. A DVI-D port forwards buffered graphics to a remote monitor for machine visualization without requiring additional converters.
