Product Description:
The CX5120-0111 is an embedded PC produced by Beckhoff for the CX Embedded PC Systems series. Designed as the central control element in automated machinery, it houses a processor, volatile memory, and persistent storage in a single compact enclosure. The device executes user logic directly at the machine level and exchanges process data with upstream networks, removing the need for a separate supervisory computer. Its architecture supports the deterministic control cycles required by motion, sequencing, and data acquisition tasks commonly found on modern production lines.
The computing core is an Intel Atom E3815 running at 1.46 GHz; the single-core design minimizes heat while providing sufficient processing capacity for PLC and visualization tasks. Runtime data reside in 2 GB of DDR3 RAM, and program files are stored on a CFast or MicroSD card accessible through the dual flash-slot arrangement. Two Ethernet controllers provide two RJ45 ports supporting 10/100/1000 Mbit/s, allowing the controller to separate fieldbus and plant networks without additional switches. The front panel has four USB 2.0 Type A connectors for service keys, operator panels, and diagnostic adapters. An integrated uninterruptible power supply provides one second of backup power during brief supply interruptions and stores 1 MB of retained data on the CFast card. The internal I/O bus draw is limited to 10 W, keeping auxiliary power requirements modest.
The controller operates from a 24 V DC supply and draws up to 11 W during normal operation, allowing it to function within restricted control-cabinet power budgets. When buffered operation is active, power consumption can rise to 18 W, which must be considered when selecting the power source and associated protective devices. Electrical isolation between the supply rails and logic circuitry is rated at 500 V, helping protect connected terminals and control electronics from transient overvoltage. The compact enclosure can be installed alongside compatible digital and analog I/O modules, while the available communication ports support connections to both machine-level and plant-level networks.
