Product Description:

The CX5020-1125 embedded controller is produced by Beckhoff and belongs to the CX Embedded PC Systems series. This DIN-rail unit combines PLC functionality with PC-based computing so that machine builders can execute deterministic control, visualization, and communication tasks on one compact device in industrial automation cells. Designed to sit beside modular K-Bus I/O terminals, it acts as the central CPU that coordinates motion, logic, and fieldbus communication in packaging lines, material-handling systems, and process skids.

At the heart of the unit is an Intel Atom Z530 processor that runs at 1.6 GHz, providing sufficient computing capacity for deterministic cycles in the TwinCAT 3 XAR runtime. The control section draws its operating power from a 24 V DC supply, and its internal power loss is rated at 12.5 W, allowing appropriate power supply and thermal system sizing. Two integrated Ethernet ports with 2 × RJ45 connectors support separate machine and plant networks without an external switch. The controller connects to remote digital and analog modules through its K-Bus interface and supplies up to 2 A of I/O backplane current, allowing several terminal slices to be powered directly. A dielectric strength of 500 Veff provides electrical isolation between the logic and field wiring.

Access for service tasks is provided through 4 × USB 2.0 ports for mass-storage devices or diagnostic dongles, while a DVI-D video output allows direct connection to an HMI panel without separate conversion hardware. The housing measures 100 mm in height, 106 mm in width, and 92 mm in depth, yet it weighs only 575 g, so it can be installed on a DIN rail without additional support. Its compact outline leaves room for neighboring I/O terminal blocks in space-limited control cabinets. The enclosed housing helps keep dust away from the internal electronics during continuous operation on the factory floor.
