The Beckhoff CX9020 Embedded PC is a powerful yet compact controller designed to meet the needs of decentralised automation systems. Powered by an Arm® Cortex®-A8 processor running at 1 GHz, this embedded PC delivers efficient performance for a broad range of control applications, from small stand-alone machines to complex distributed architectures. Its combination of processing capability, integrated interfaces, and rugged design makes it a highly versatile solution for industrial automation.

Memory resources are well balanced for its intended role. The CX9020 comes with 1 GB DDR3 RAM, ensuring smooth execution of automation tasks and applications, alongside two microSD card slots, one of which is supplied with a 512 MB card. Storage capacity can be expanded as needed, allowing engineers to adapt the device to meet the requirements of different applications. This flexibility provides both reliable program storage and easy serviceability.

Connectivity is one of the CX9020’s strengths. It includes two Ethernet ports (10/100 Mbit/s) with an integrated switch, making it simple to connect to both control networks and higher-level IT systems. A DVI-D port provides a direct display output for visualisation or HMI applications, while four USB 2.0 ports enable the connection of peripherals such as input devices, diagnostic tools, or external storage. An optional interface slot further enhances adaptability, allowing for additional communication options tailored to specific system needs.

The device also provides clear and practical diagnostic indicators on its front panel, including LEDs for power, TwinCAT status, flash access, and bus communication. These at-a-glance diagnostics support quick troubleshooting and system monitoring, helping engineers maintain system uptime and reliability.

Designed for the rigours of industrial use, the CX9020 employs passive cooling, eliminating the need for moving parts such as fans. This design ensures long service life, reduced maintenance requirements, and reliable performance even in environments with vibration, dust, or temperature fluctuations. Its compact size makes it easy to integrate into space-constrained control cabinets while still providing the functionality of a high-performance controller.

The CX9020 runs Windows Embedded Compact 7 (English), offering a stable and lightweight operating system optimised for automation. When paired with Beckhoff’s TwinCAT automation software, the device functions as a powerful PLC, motion controller, and automation hub. Engineers benefit from a consistent software environment across Beckhoff’s hardware platform, reducing programming effort and simplifying scaling from small to large automation systems.

In practice, the CX9020 combines processing performance, connectivity, and industrial robustness in a compact, fanless housing. It enables cost-effective and reliable control solutions for industries such as machine building, logistics, packaging, and building automation. With its modular expandability and wide range of interfaces, the CX9020 offers a future-ready platform for efficient and precise automation control.
