Product Description:

The CX9020-0115 is an embedded PC manufactured by Beckhoff and delivered within the CX Embedded PC Systems series. It integrates processing, memory, and fieldbus coupling into a single rail-mount enclosure that functions as a programmable logic controller, communication gateway, and visualization node in industrial plants. By attaching directly to E-bus or K-bus terminal stacks, the unit becomes the control core of distributed I/O stations, coordinating real-time tasks without the footprint of a panel PC. Passive heat dissipation keeps moving parts out of the housing, helping the controller run continuously in material-handling, packaging, and building-automation equipment.

The control layer executes on TwinCAT 3 Runtime (XAR), allowing IEC 61131-3 logic, motion, and HMI modules to run locally. A single-core Arm Cortex-A8, 1 GHz processor supplies deterministic execution while maintaining low energy demand. Program and buffer data reside in 1 GB DDR3 RAM, which is ample for medium-sized projects that include trend logging and alarm lists. The electronics draw from a 24 V DC control supply, and overall consumption stays below 5 W, minimizing power-supply sizing and cabinet heat load.

Physical integration centers on a compact housing measuring 84 × 100 × 91 mm, so the PC fits beside standard terminal blocks without blocking airflow. Four front-mounted USB 2.0 ports accept touchscreens, service sticks, or barcode readers, while Two switched RJ45 10/100 Mbit/s interfaces support line-topology networking or separation of plant and service segments. The controller carries an IP20 protection class that is suitable for enclosed panel environments with limited dust ingress. Dual microSD slots, 128 kB of NOVRAM for retain variables, and a 2 A feed to the terminal bus provide nonvolatile storage and I/O power needed to preserve process data during power interruptions.
