Product Description:
The CX5140-0122 is a compact embedded PC produced by Beckhoff within the CX Embedded PC Systems series. This fanless module functions as the central controller in distributed I/O or motion platforms, merging PLC, HMI, and axis control in one DIN-rail package. By executing deterministic control code on its onboard operating system, it coordinates sensors, actuators, and fieldbus networks used in machine tools, packaging lines, and building services. Its embedded format is well suited to control cabinets that need reliable automation performance without the footprint of a full industrial workstation.
The computing core is an Intel Atom E3845 1.91 GHz processor that integrates four execution units, and its 4 CPU cores allow separate logic, communication, and visualization threads to run in parallel without cycle-time conflicts. A dedicated memory controller serves 4 GB DDR3-RAM, giving the real-time kernel enough space for object dictionaries, motion profiles, and user interfaces. Graphics output uses a base frequency of 542 MHz, and the integrated engine shares 256 MB of VRAM to refresh local panels or remote desktop sessions without relying on external GPUs. This balance of processing and memory supports multitasking workloads in which field communication, visualization updates, and motion control run at the same time. These resources support software PLC tasks, soft-motion interpolation, and data logging while maintaining deterministic scan times.
Installation parameters support cabinet integration. The aluminum housing measures 100 mm in height, 142 mm in width, and 92 mm in depth, and the shape leaves room for fieldbus extensions on either side while keeping the protection rating of IP20. A 24 V rail supplies the electronics; the logic accepts 24 V DC and draws 16 W during standard operation or up to 23 W when the optional UPS is attached. Interfaces include two Gigabit LAN sockets on 2 × RJ45 connectors and 4 × USB 2.0 ports for backup media or service adapters. The front-facing connections support direct access for network links, removable storage, and local maintenance devices. The TwinCAT 2 NC PTP runtime ships preinstalled, enabling axis-synchronous positioning as soon as configuration is loaded.
