Product Description:
The CX5120-0113 belongs to the Beckhoff CX Embedded PC Systems series and functions as a compact DIN-rail industrial controller. Beckhoff integrates the CPU, memory, fieldbus connections, and optional data storage in one housing so the unit can execute PLC logic, HMI tasks, or gateway services directly on the machine. Within an automation cabinet, it replaces a traditional industrial PC and separate communication modules, reducing wiring and footprint while maintaining the dielectric strength required for 500 V isolation between the supply and I/O circuitry.
The processing section uses an Intel Atom E3815 processor operating at 1.46 GHz with a single core. A 2 GB DDR3 RAM block stores the operating system and real-time application data, and its bandwidth supports deterministic task scheduling. Overall power demand has a maximum of 11 W, so the controller adds little heat to the cabinet. The compact housing measures 122 × 100 × 92 mm, allowing tiered mounting alongside Beckhoff I/O terminals. The two RJ45 Gigabit Ethernet ports supporting 10/100/1000 Mbit/s provide separate channels for control networks and plant-level data. These independent connections can support redundant networks or segregated traffic without requiring additional network interfaces.
Stable operation relies on a field power supply of 24 V DC, which powers the logic and an internal uninterruptible power supply. The internal power supply can bridge an interruption for 1 second, helping prevent file system corruption during a brief loss of input power. The front panel provides four USB 2.0 ports rated at 500 mA each for scanners, storage devices, or wireless adapters without external hubs. Nonvolatile media can be inserted through the CFast and microSD slots located under the removable side cover. These slots support software updates and recipe transfers while the front face retains its IP20 protection. The accessible media and peripheral connections allow the controller to handle local storage and external devices without occupying additional DIN-rail space.
