Product Description:
The CX5120-0135 embedded PC belongs to the CX Embedded PC Systems series produced by Beckhoff. Intended for mid-range machine control and data handling, the module combines real-time logic, motion coordination, and visualization in a fanless DIN-rail format. It attaches directly to Beckhoff’s terminal blocks so that process signals reach the CPU without intermediate wiring, and it supplies supervisory capabilities for drives, sensors, and fieldbuses used in industrial automation cells.
Its computing core is an Intel Atom E3815 1.46 GHz processor supported by 2 GB DDR3-RAM. A single physical core schedules the TwinCAT tasks, and deterministic performance is aided by 256 MB of shared graphics memory. Data logging and boot images reside on CFast and MicroSD media mounted on removable trays. Network communication passes through 2 × RJ45 10/100/1000 Mbit/s interfaces that can operate as EtherCAT masters or standard Ethernet links. External peripherals connect by 4 × USB 2.0 Type A sockets, each rated at 500 mA. The controller accepts a 24 V DC supply, and internal conversion delivers 10 W to attached E-bus or K-bus terminals. The electronics are protected against transient contact voltage up to 500 V because of the dielectric barrier between the supply and logic.
Total system demand stays within 11 W under typical load, so panel temperatures remain moderate even in enclosed cabinets. An internal UPS circuit can draw up to 18 W of charge power to maintain volatile data during brief outages. The on-chip graphics engine runs at 400 MHz, which is sufficient for local HMI pages rendered through the shared memory buffer. Machine logic, axis control, and diagnostics execute under TwinCAT 3 Runtime (XAR), allowing IEC 61131-3 programming and Windows-independent real-time scheduling alongside user software. The CX5120-0135 supports local control, diagnostics, and visualization without a separate PC.
