Product Description:

Beckhoff’s CX5130-0125 embedded PC belongs to the CX Embedded PC Systems series. It is intended to act as the central PLC, motion controller, and HMI host in distributed automation cells. By combining an Intel Atom processor with fieldbus and I/O interfaces, the device runs real-time logic, visualization, and data logging directly on the DIN rail without an external industrial PC. Within a compact housing, it offers enough computing power for mid-range machines while maintaining the wiring and form factor typical of a conventional terminal block.

The computing core is an Intel Atom E3827 running at 1.75 GHz and equipped with 2 logical cores, enabling deterministic execution of TwinCAT 3 Runtime tasks as well as standard Windows services. A dedicated 4 GB DDR3-RAM module handles code, HMI graphics, and buffered process data. Mass storage is provided through a CFast slot and a MicroSD slot, so storage media can be exchanged without opening the enclosure. Communication to supervisory networks and EtherCAT terminals is handled through 2 × RJ45, 10/100/1000 Mbit/s ports, and peripheral devices such as service keyboards or barcode scanners connect through 4 × USB 2.0, 500 mA ports. A built-in UPS bridges 1 s of supply loss and retains 1 MB of volatile process variables for orderly shutdown.

The system draws a maximum of 14 W and operates from a single 24 V DC control circuit, simplifying cabinet power distribution. Its electronics withstand a dielectric strength of 500 V between supply and ground, supporting isolation requirements found in machinery safety standards. Housed in a fanless package that measures 142 mm × 100 mm × 92 mm, the PC fits beside standard terminal modules while keeping a slim depth. The enclosure carries an IP20 rating, so it must be installed in a protected cabinet but offers finger-safe access to connectors.
