Product Description:
The CX5020-1111 is an embedded PC module offered by Beckhoff within the CX Embedded PC Systems series. As a DIN-rail-mounted controller, it combines PC technology with modular I/O to serve as the central controller for small to midrange machine cells. In an automation line, it hosts the real-time PLC and directly controls fieldbus terminals, replacing separate PLCs and industrial PCs with one compact device. Designed for continuous operation in control cabinets, it integrates processing, communication, and visualization functions in a single housing.
At its core, a 1.6 GHz Intel Atom Z530 processor uses a single processing core to provide deterministic execution for the included TwinCAT 2 PLC Runtime. Program code and retained data are stored on 128 MB of CompactFlash storage, so the system can boot without a rotating disk. Two RJ45 adapters support 10/100/1000 Mbit/s Ethernet for configuration access, OPC communication, or EtherCAT gateway routing, while a DVI-D port drives a local HMI and four USB 2.0 sockets connect peripheral devices. The internal K-Bus backplane links digital and analog terminals, and a dedicated bus output can supply 2 A to the I/O terminals. The embedded PC dissipates only 12.5 W at full load, which simplifies passive cabinet ventilation and reduces thermal stress on internal components.
Electrical integration is straightforward because the unit accepts a 24 V DC supply commonly used in control panels. The primary circuitry is electrically isolated from the low-voltage bus with a dielectric strength of 500 Veff, helping protect adjacent sensors and drives. The enclosure measures 100 × 106 × 92 mm, allowing dense installation next to terminal blocks without obstructing airflow. Its IP20 rating is suitable for standard cabinet environments where direct contact with liquids is not expected. The aluminum housing helps dissipate heat from the processor, and the operating current drawn from the 24 V rail remains suitable for typical auxiliary power supplies. Because a single CPU core handles the PLC cycle, I/O latency remains predictable, and the K-Bus can be expanded without changing the controller housing dimensions.
