Product Description:
The CX2020-0125 is an embedded PC produced by Beckhoff within the CX Embedded PC Systems series. Intended for DIN-rail installation, this unit merges PC processing, PLC logic, and HMI capabilities so a single device can coordinate motion, handle fieldbus traffic, and render visualization screens. In automated machinery, it functions as the central controller, executing TwinCAT tasks, collecting I/O data, and interfacing with higher-level networks while occupying minimal cabinet space. That arrangement allows smaller control systems to use one compact platform for machine logic and operator-facing functions.
Its computing subsystem centers on a 1.4 GHz single-core Intel Celeron 827E processor. The single core and clock rate suit PLC cycle times below one millisecond when TwinCAT 3 XAR acts as the control software. A soldered 2 GB DDR3-RAM module stores real-time variables, and 128 kB NOVRAM secures retentive data during power loss. Compact mechanics of 144 x 99 x 91 mm simplify placement in shallow enclosures. The electronics draw power from a 24 V DC supply that also feeds attached CX-series expansion modules. Two RJ45 connectors provide separate machine and plant segments, and their controller chips support EtherCAT as a distributed I/O backbone. This layout keeps computing, networking, and local expansion in one DIN-rail node.
Total power demand does not exceed 21 W, keeping heat generation compatible with fanless cooling. Each Ethernet interface reaches the full 10/100/1000 Mbit/s data rate for deterministic field communication. External peripherals attach through four front-mounted ports in a 4 x USB 2.0 configuration, and each port can deliver 500 mA for service panels or data keys. Integrated graphics allocate 128 MB of shared memory and operate from a 350 MHz base clock, enabling basic HMI display without an additional GPU. The front-facing connections also make routine access straightforward when removable storage, keyboards, or service displays need to be connected temporarily.
