Product Description:

The CX2042-0155 is an embedded PC manufactured by Beckhoff and supplied as part of the CX Embedded PC Systems series. As a modular DIN-rail controller, it unifies PLC, motion, and visualization tasks in one unit for machine-level automation. The controller mates directly with Beckhoff I/O terminals to create distributed nodes, letting it execute deterministic control while communicating with higher-level networks. By combining PC technology with fieldbus interfaces, the device serves real-time roles that once required separate PLC hardware.

At its core, an Intel Xeon D-1527 processor runs at 2.2 GHz and offers 4 processing cores, giving capacity for motion calculations and data logging under TwinCAT 3 Runtime (XAR). The CPU is linked to 8 GB DDR4 RAM, so large real-time tasks and HMI datasets remain in memory without paging. Graphics output is delivered by the AMD E8860 GPU, and its 2 GB GDDR5 frame buffer supports multi-display visualization as well as hardware-accelerated OpenCL routines. Nonvolatile data that must survive power loss is stored in 128 kB NOVRAM, while a 2 A I/O terminal current powers attached digital or analog slices without an external feed. This combination supports control, data logging, and visualization functions in one compact unit.

The hardware operates from a 24 V DC supply and, under full load, draws up to 95 W, so the required power source and cooling path can be sized appropriately. Dielectric strength of 500 V protects logic from field wiring, and the power contacts can pass 10 A to downstream terminals for high-current actuators. The housing measures 204 × 99 × 91 mm and weighs 1650 g, allowing installation beside standard I/O slices without exceeding common rail depths. The compact enclosure helps the controller fit into DIN-rail layouts that place computing hardware next to field I/O.
