Product Description:
The CX2020-0155 is an embedded PC manufactured by Beckhoff and assigned to the CX Embedded PC Systems series. Installed on a DIN rail inside the control cabinet, it combines x86 computing with direct I/O expansion. This allows it to execute PLC and motion functions in real time for automated equipment, including compact machines that require cabinet-mounted control hardware.
An Intel Celeron 827E processor clocked at 1.4 GHz drives the unit and is supported by a single processing core, making deterministic cycle times easier to predict. The main memory is 2 GB DDR3-RAM, which stores active program code and variables, while 128 MB of shared graphics memory handles visualization tasks delivered through the DVI-I port. A CFast slot ships with at least 40 GB of solid-state storage for the operating system and TwinCAT project files. Even under maximum computational and communication load, electrical demand remains limited to 21 W, helping cabinet power sizing and thermal planning remain accurate. Two Gigabit Ethernet ports permit controller networking or fieldbus coupling, and four USB 2.0 ports rated at 500 mA each support service devices or additional interfaces.
Electrical insulation inside the housing withstands up to 500 V of dielectric strength between supply and signal circuits, and the PC itself is powered from a 24 V DC source that is common in machinery panels. The integrated graphics controller can output up to 1920 × 1200 pixels, allowing high-resolution HMI screens without extra hardware. For fail-safe data such as production counters, a 128 kB NOVRAM keeps the values persistent during a power loss. The enclosure measures 144 × 99 × 91 mm, so space remains for terminal modules on either side. TwinCAT 3 Runtime (XAR) is preinstalled, so deterministic task scheduling and fieldbus stacks start as soon as power is applied. The two RJ45 LAN ports and the USB connectors on the front simplify wiring when the controller is deployed on automated lines.
