Product Description:
The CX2020-0123 is an embedded PC manufactured by Beckhoff and belongs to the CX Embedded PC Systems series. Designed as a DIN-rail PLC and motion platform, it combines real-time control, networking, and visualization duties for conveyors, process skids, and building management stations. Fieldbus terminals plug directly into the controller, allowing decentralized I/O to be scanned and executed under deterministic cyclic tasks generated by the integrated automation runtime. Its compact format lets control, communication, and local interface functions remain in one cabinet-mounted unit.
At the heart of the unit is an Intel Celeron 827E processor with a single core that operates at 1.4 GHz. This CPU works with 2 GB DDR3-RAM for program code, data, and operating system services, while 128 kB NOVRAM secures persistent process variables against power loss. Control logic is executed by the TwinCAT 2 NC-I Runtime, which allows interpolated axis control to run alongside soft-PLC tasks on the same controller. Two onboard communication channels, 2 x RJ45 Gigabit Ethernet, permit separation of machine traffic from service connections, and an array of 4 x USB 2.0 sockets supports removable storage, barcode readers, or panel interfaces.
The hardware is supplied from a 24 V DC cabinet rail and draws up to 21 W when all interfaces are active. Internal backplane lines forward a 2 A supply to the I/O terminals, while the power contacts can carry 10 A to downstream modules such as high-current relays. Electrical insulation withstands 500 V dielectric stress between supply domains, supporting safe separation of field and logic circuits. The enclosure meets IP 20 requirements, so it is intended for closed control cabinets, and its compact form factor of 144 × 99 × 91 mm helps conserve rail space next to drives and breakers.
