CX5020-0125 | BECKHOFF | Module CPU

Description

Designed to deliver robust and deterministic control for medium-sized automation systems, the CX5020-0125 Embedded PC is a compact, DIN rail-mountable controller featuring a 1.6 GHz Intel Atom® Z530 processor. This hardware unit functions as a high-density PLC and motion controller, executing complex control tasks through integrated software runtimes. It is engineered with automatic bus recognition, allowing direct physical connection and communication with both Beckhoff K-bus terminals and high-speed EtherCAT E-bus systems.

The unit incorporates comprehensive connectivity interfaces directly on its compact housing, minimizing the footprint within industrial control enclosures. It includes dual independent Gigabit Ethernet ports, multiple USB 2.0 interfaces, and a dedicated DVI-D output for direct human-machine interface (HMI) connection. To ensure high data integrity during unplanned power losses, the CX5020-0125 is equipped with an integrated 1-second UPS that writes persistent variables to an exchangeable Compact Flash card.

Features

• Single-core Intel Atom® Z530 processor operating at 1.6 GHz clock speed.
• Automatic physical bus detection supporting both E-bus (EtherCAT) and K-bus terminal connections.
• Integrated hardware-based 1-second UPS protecting up to 1 MB of critical data on the Compact Flash card.
• Fanless configuration utilizing passive convective cooling for extended operational longevity.
• Comprehensive onboard interfaces: 2 x RJ45 Gigabit Ethernet, 4 x USB 2.0, and 1 x DVI-D.
• Diagnostics LED cluster providing real-time feedback on power status, TwinCAT status, flash card access, and bus communication.

Applications

• Distributed PLC and decentralized motion control in packaging and assembly plants.
• Process control systems requiring reliable industrial communication networks.
• Power generation and substation monitoring using standard industrial Ethernet protocols.
• Building automation and environmental control systems with localized visual feedback.

Connections and Interfaces

Installation Guidelines

• Mount the module horizontally on a standard 35 mm DIN rail (EN 60715) inside a closed control cabinet.
• Ensure a minimum clearances of 30 mm above and below the device to allow adequate convection airflow through the cooling ribs.
• Verify that the mounting rail is connected to the functional earth of the cabinet before applying power.
• Insert or remove the Compact Flash card only when the power supply to the controller is fully switched off to prevent data corruption.

Compliance and Certifications

• CE, UL
• ATEX: II 3 G Ex nA IIC T4 Gc (only applicable when configured with CX1900-0105 ordering option)
