Description

Designed as a compact, DIN rail-mountable controller, the Beckhoff CX5020-0121 belongs to the high-performance CX5000 Embedded PC series. This control unit features a fanless design powered by an Intel Atom Z530 processor running at 1.6 GHz, offering a robust processing environment for industrial automation applications. Utilizing dual-bus compatibility, the module automatically detects and interfaces with both EtherCAT Terminals (E-bus) and standard Bus Terminals (K-bus), providing highly versatile I/O integration. The CX5020-0121 acts as a centralized controller capable of running TwinCAT 2 or TwinCAT 3 (XAR) PLC and Motion Control software, making it ideal for distributed control systems and manufacturing execution platforms.

Features

Intel Atom Z530 single-core processor operating at a 1.6 GHz clock frequency.
Integrated dual-bus interface supporting automatic E-bus (EtherCAT Terminals) and K-bus (Bus Terminals) recognition.
Built-in 1-second UPS utilizing 1 MB of persistent data stored directly on a Compact Flash card.
Dual independent Gigabit Ethernet RJ45 interfaces to facilitate seamless network integration.
Flexible display support through an integrated DVI-D graphic interface.
Equipped with four high-speed USB 2.0 ports and one option slot for customizable communication interfaces.
Fanless design ensures highly reliable operation in harsh industrial environments.

Installation Guidelines

Mounting: Mount the module horizontally on a standard 35 mm DIN rail (EN 60715) within a secure IP54-rated control enclosure.
Ventilation: Ensure a minimum clearance of 30 mm above and below the device to permit adequate natural convection cooling in fanless systems.
Grounding: Connect the integrated PE contact on the DIN rail or backplane terminal directly to the central functional earth terminal of the control cabinet.
Power Cabling: Use copper conductors rated for at least 75 Celsius and properly sized to meet the 24 V DC (-15% / +20%) supply tolerance requirements.
