Product Description:
The CX5120-0130 is an embedded PC manufactured by Beckhoff for the CX Embedded PC Systems series. Mounted on a DIN rail, this unit combines PLC logic, motion coordination, and visualization within one enclosure, giving machine builders a compact real-time controller for distributed I/O and drive technology. Its architecture supports the TwinCAT runtime, allowing the device to coordinate deterministic fieldbus cycles while hosting Windows or Embedded Linux user interfaces for plant-level supervision.
Processing tasks are handled by an Intel Atom E3815 single-core processor operating at 1.46 GHz; this clock frequency balances execution speed with low thermal dissipation for fanless operation. The system includes 2 GB of DDR3 RAM, providing capacity for the operating system, motion libraries, and buffered user data without excessive paging delays. Two RJ45 ports support network speeds of 10/100/1000 Mbit/s, so one interface can serve as a machine bus while the second connects to a supervisory LAN or remote service connection. The control electronics receive power from a regulated 24 V DC input, and an internal power path delivers up to 10 W to attached E-bus or K-bus terminal stacks, reducing the need for additional power injectors on moderate I/O rail lengths.
The housing measures 122 × 100 × 92 mm, allowing the embedded PC to sit beside standard slice I/O modules without exceeding typical enclosure depths. Maximum system power consumption is limited to 11 W, supporting convection cooling and the use of small uninterruptible power supplies for backup. Four front-panel connectors provide four USB 2.0 Type-A ports for flash drives, wireless adapters, input devices, or local data capture. The enclosure has an IP20 protection rating for installation inside dry control cabinets, while 256 MB of dedicated graphics memory supports panel displays through the integrated DVI-I output without diverting main memory from control processes.
