Description

Engineered for medium-scale automation applications, the CX5120-0143 embedded PC functions as a compact, DIN-rail-mountable controller utilizing an Intel Atom E3815 single-core processor running at 1.46 GHz. This industrial-grade embedded PC features hardware-assisted virtualization and integrated diagnostic indicators, facilitating real-time execution of complex PLC, motion control, and visualization tasks. It supports dual-bus compatibility, enabling automatic recognition and communication with both E-bus (EtherCAT) and K-bus (Bus Terminal) I/O systems.

The system comes equipped with 2 GB DDR3 RAM and an integrated 1-second UPS (Uninterruptible Power Supply) that stores up to 1 MB of persistent data on a CFast card. It offers diverse interface options, including two independent Gigabit Ethernet ports, a DVI-I video output, and four USB 2.0 ports, alongside a slot for optional hardware interfaces.

Features

  • Intel Atom E3815 processor (1.46 GHz, single core)
  • Dual-bus I/O connection with automatic recognition for E-bus and K-bus terminals
  • Integrated 1-second UPS (saves 1 MB of persistent data onto CFast card)
  • Robust Selection of physical interfaces: 2 x RJ45 ports (10/100/1000 Mbit/s), 1 x DVI-I, 4 x USB 2.0
  • Flexible operating system compatibility including TwinCAT/BSD, Windows Embedded Compact 7, Windows Embedded Standard 7 P, and Windows 10 IoT Enterprise
  • Diagnostics LEDs for Power, TwinCAT status, Flash access, and Bus status
  • Internal battery-backed real-time clock (exchangeable battery)

Applications

  • Industrial automation and process control systems
  • Machine tool automation and visualization (HMI)
  • Power generation and distribution monitoring
  • Water and wastewater treatment facilities
  • Building automation and smart infrastructure
