Description

Designed for space-saving DIN rail mounting, the Beckhoff CX5120-0100 serves as a robust fanless controller within the CX5100 Embedded PC series. This industrial PC features an energy-efficient Intel Atom E3815 single-core processor operating at 1.46 GHz, making it well-suited for medium-scale automation tasks requiring direct EtherCAT or Bus Terminal integration. The module includes dual independent Gigabit Ethernet ports, USB 2.0 connectivity, and a DVI-D display interface, allowing for direct visual monitoring and fast network integration.

The controller is equipped with 2 GB of non-expandable DDR3 RAM and features separate slots for CFast and microSD cards to manage operating systems and application data. An integrated 1-second UPS protects volatile memory by saving up to 1 MB of persistent data to the CFast card during power loss events. For flexible I/O configurations, the CX5120-0100 automatically detects and supports either E-bus (EtherCAT) or K-bus (Bus Terminals) connections. Note that this specific model variant is delivered without a pre-installed operating system or TwinCAT runtime license, allowing custom software provisioning.

Features

  • Single-core Intel Atom E3815 processor (1.46 GHz clock speed)
  • 2 GB DDR3 RAM onboard system memory
  • Dedicated slots for CFast card and microSD storage media (cards not included)
  • Integrated 1-second UPS for up to 1 MB of persistent diagnostic data retention
  • Automatic recognition and control of K-bus (standard Bus Terminals) and E-bus (EtherCAT Terminals)
  • High-density peripheral interfaces: 2 x RJ45 Gigabit Ethernet, 4 x USB 2.0, and 1 x DVI-D
  • Diagnostic LEDs indicating power status, TwinCAT state, flash access, and fieldbus communication activity

Applications

  • Industrial process control and automated machinery
  • Energy management systems and power distribution tracking
  • Water treatment and environmental monitoring infrastructure
  • Building management systems and HVAC plant coordination
  • High-speed industrial Ethernet and standard fieldbus integration

Installation Guidelines

  • Mounting Location: Install horizontally on a standard 35 mm DIN rail (EN 60715). Ensure correct positioning to allow natural thermal convection.
  • Clearance Requirements: Keep a minimum ventilation space of 30 mm above and below the device to prevent thermal buildup in fanless configurations.
  • Earthing: Connect the functional earth terminal via the DIN rail connection and ensure low-resistance system grounding.
  • Power Cabling: Use appropriate copper wiring sized to handle the 24 V DC input and the auxiliary I/O terminal supply current.

Compliance and Certifications

  • CE, UL
