Product Description:
The CX2020-0135 is an embedded PC produced by Beckhoff as part of the CX Embedded PC Systems series. Designed to slot directly onto a DIN rail next to I/O terminals, the unit serves as a compact control platform for PLC, motion, and HMI tasks on the plant floor. By combining an industrial CPU, fieldbus interfaces, and solid-state storage inside a single enclosure, the device replaces separate controller, gateway, and visualization hardware in distributed automation architectures. Its slim DIN-rail format also suits modular control cabinets where the controller and terminal stack must fit within a narrow installation space.
The computing core is an Intel Celeron 827E, 1.4 GHz single-core processor, supported by 2 GB DDR3-RAM for real-time execution of control tasks. Two Gigabit ports supplied via 2 × RJ45, 10/100/1000 MBit/s links connect higher-level networks and EtherCAT field devices without an external switch. The system draws control power from a 24 V DC supply rail, and at full load it limits demand to 21 W, which helps when panels have tight power budgets. Isolated backplane pins deliver 2 A to local I/O slices, while separate power contacts can pass 10 A to downstream terminals. A dielectric strength rating of 500 V provides isolation between the internal logic and the field wiring segments.
Data retention and multimedia handling are addressed by a 40 GB CFast card, 128 kB of non-volatile NOVRAM for process images, and 128 MB of shared graphics memory that drives a DVI monitor through the optional interface module. Four front-mounted connectors provide 4 × USB 2.0, 500 mA each for service tools or touch screens, giving convenient access for removable media and input devices. The fanless aluminum housing measures 144 × 99 × 91 mm and carries the IP20 protection class, so it is intended for installation inside a switch cabinet. Compliance with TwinCAT 3 XAR control software supports deterministic task scheduling and smooth integration with the Beckhoff I/O environment.
