Product Description:

The CX5020-0121-1003 is an embedded PC module produced by Beckhoff within the CX Embedded PC Systems series. The unit combines a compact industrial computer and a modular I/O interface so it can act as the central controller in machine cells, conveyor lines, and building automation networks. It hosts real-time control software and fieldbus couplers to execute PLC logic directly on the DIN rail. Its compact format also helps keep control cabinets organized when the controller is installed beside power supplies, terminals, and communication modules.

Processing is handled by an Intel Atom Z530 processor that operates at 1.6 GHz, delivering deterministic cycle times for the integrated TwinCAT 2 PLC Runtime. The module draws its logic supply from a 24 V DC (-15 %/+20 %) source and limits dissipation to 12.5 W, which helps keep cabinet temperatures within operating limits. Two independent Ethernet ports, provided as 2 × RJ45 connectors that support Gigabit and Fast Ethernet rates, allow separation of control and diagnostics networks without an external switch. Remote terminals attach through the E-Bus backplane, and a 2 A I/O feed is available for local sensors. Dielectric strength of 500 Veff isolates the low-voltage domain from the field level during hot-swapping of I/O slices.

The controller runs Windows Embedded Standard 2009 beside the real-time kernel, so HMI services and data logging can coexist with time-critical control tasks. Four external peripherals, such as scanners or flash drives, attach via 4 × USB 2.0 ports, while a DVI-D output drives an external display. Environmental limits for reliable operation range from -25 °C to +60 °C, and storage is permitted down to -40 °C and up to +85 °C when the plant is idle. The housing meets IP20, so it must be placed inside a cabinet, but passive cooling eliminates the need for forced airflow. Physical size is contained to 100 × 106 × 92 mm, which matches other CX-series CPU slices and allows direct side-by-side mounting with power supplies and fieldbus masters.
