Product Description:
The CX5020-1122 embedded PC controller is produced by Beckhoff for the CX Embedded PC Systems series. It combines a low-power CPU, fieldbus coupler, and local terminal interface in one DIN-rail housing. This integrated arrangement allows it to execute PLC logic, HMI tasks, and data logging directly inside a control cabinet without requiring an external computer. Its compact format also allows the controller to be positioned near connected automation components, reducing the distance required for cabinet wiring.
The computing section is powered by an Intel Atom Z530 processor that operates at 1.6 GHz, providing deterministic task switching for TwinCAT real-time workloads. All electronics are supplied from a single 24 V DC input, which simplifies cabinet wiring and matches common machine-control power rails. Two RJ45 Ethernet ports with 10/100/1000 Mbit/s speeds support switched or routed network topologies, while the built-in Intel GMA 500 graphics core drives touch panels or monitors through the DVI-D output. The unit measures 100 × 106 × 92 mm, allowing installation alongside Beckhoff I/O slices on the K-Bus terminal bus. Its IP20 protection class is suitable for clean control enclosures that prevent direct contact with internal electrical parts. Convection airflow removes operating heat without requiring additional cooling equipment inside the controller.
Thermal dissipation does not exceed 12.5 W, so no fan is required for normal operation. The I/O backplane can draw up to 2 A from the internal supply to energize connected digital sensors and actuators. The power stage provides up to 500 V RMS of dielectric strength between the supply and housing, helping isolate the electrical input from the enclosure. Four front-mounted USB 2.0 sockets accept mass-storage media, input devices, or service tools. A one-second UPS backup bridges brief power interruptions to help preserve file integrity before the system shuts down. Video output is provided through a DVI-D connector, and data from upstream controllers can be forwarded to downstream terminals over the K-Bus without additional gateways.
