Beckhoff CX2020-0135 Embedded PC

The Beckhoff CX2020-0135 is a rugged, high-performance Embedded PC tailored for advanced automation, PLC, and motion control applications. Built around a 1.4 GHz Intel® Celeron® 827E processor, this fanless, solid-state controller is optimized for demanding industrial environments with zero moving parts for enhanced reliability.

This model includes 2 GB DDR3 RAM as standard (expandable to 4 GB), 20 GB or 40 GB CFast flash storage, and 128 kB NOVRAM to retain critical data during power loss without the need for a UPS. It features dual Gigabit Ethernet interfaces, four USB 2.0 ports, one DVI-I output, and supports optional fieldbus or serial interfaces. Up to four PCI Express® expansion modules can be added for flexible field deployment.

With compatibility for Windows Embedded, Windows 10 IoT Enterprise 2016 LTSB, and TwinCAT/BSD, the CX2020-0135 supports both TwinCAT 2 and TwinCAT 3 runtimes, including interpolated motion via TwinCAT NC I.
