The Beckhoff CX8090 Embedded PC is a compact and versatile controller designed to provide efficient performance for distributed automation applications. Equipped with an ARM9™ processor clocked at 400 MHz, it offers the right balance of computational power and energy efficiency for small to medium-sized control systems.

The system comes with 64 MB DDR2 RAM (non-expandable), which ensures stability in executing real-time control tasks. For data storage, it features a microSD card slot with a 512 MB card included, expandable as needed to accommodate project data, logging, or additional program storage. To protect process-critical information, the CX8090 includes an integrated 1-second UPS, capable of storing 1 MB of data directly to the microSD card in the event of a power failure, helping ensure system resilience and quick recovery.

A standout feature of the CX8090 is its integrated 2-port Ethernet switch (10/100 Mbit/s), which enables flexible networking options. With dual RJ45 ports, the device supports line topology, daisy chaining, or star network configurations, reducing the need for external switches and simplifying system wiring. This makes it ideal for distributed architectures in machine building, process control, and building automation.

The CX8090 is programmed using the IEC 61131-3 standard, providing compatibility with multiple programming environments and flexibility in implementing structured, functional block, or object-oriented programming methods. It is fully integrated into Beckhoff’s TwinCAT automation software, turning the device into a complete PLC and motion controller when required.

In terms of connectivity, the unit offers one USB device interface (hidden behind the front flap) for configuration or connecting peripherals, as well as a bus interface for direct connection to Beckhoff’s modular I/O systems. It supports both E-bus and K-bus terminals, automatically recognising the type of bus used, thereby simplifying expansion with digital, analog, or specialised I/O modules.

The CX8090 employs passive cooling, ensuring reliable, maintenance-free operation without the need for moving parts. Its compact form factor allows easy installation in control cabinets and decentralised systems where space is limited. Despite its size, the device delivers robust performance across a variety of industries, including factory automation, HVAC, energy systems, and material handling.

In summary, the Beckhoff CX8090 Embedded PC provides a cost-effective, reliable, and space-saving control solution with integrated networking capability. Featuring a 400 MHz ARM9™ processor, dual Ethernet ports, integrated UPS, and seamless TwinCAT compatibility, it is ideally suited for small to medium automation tasks that demand efficiency, flexibility, and robust communication in a compact package.
