BECKHOFF CX5020-1115 Embedded PC CPU Module

Description

The BECKHOFF CX5020-1115 is a compact, DIN rail-mountable Embedded PC CPU module designed for demanding industrial automation and control tasks. Powered by an Intel Atom Z530 processor with a 1.6 GHz clock frequency, this single-core controller provides a balance of performance and thermal efficiency in a robust, fanless form factor. It serves as a central controller within the Beckhoff control system architecture, managing complex automation sequences, fieldbus communications, and user applications.

A key capability of the BECKHOFF CX5020-1115 is its dual I/O bus interface, which features automatic recognition for both EtherCAT Terminals (E-bus) and standard Bus Terminals (K-bus). This design allows engineers to build highly flexible local I/O configurations or seamlessly integrate existing systems without changing hardware platforms. Additionally, an integrated 1-second UPS provides persistent memory protection, writing up to 1 MB of critical data to the Compact Flash card during power losses to prevent system data corruption.

Equipped with dual independent Gigabit Ethernet ports, a DVI-D display interface, and four USB 2.0 ports, this controller offers diverse connectivity options for networking, visualization, and peripheral integration. Its high-quality physical construction supports reliable operation across an extended temperature range, making it suitable for standard and harsh industrial environments alike.

Features

• Single-core Intel Atom Z530 processor with 1.6 GHz clock frequency
• Automatic recognition interface for EtherCAT Terminals (E-bus) and Bus Terminals (K-bus)
• Integrated 1-second UPS for persistent data retention (up to 1 MB saved to Compact Flash)
• Dedicated Compact Flash card slot with 128 MB CF card included for reliable storage
• Dual RJ45 Gigabit Ethernet ports (10/100/1000 Mbit/s) for independent network structures

Installation Guidelines

1. Ensure the 24 V DC system power supply is fully de-energized before mounting, wiring, or servicing.
2. Mount the CX5020-1115 CPU module vertically onto a standard 35 mm DIN rail (EN 60715) by snapping the rear locking mechanism onto the rail.
3. Maintain appropriate clearance above and below the unit to permit passive convective airflow, avoiding external heat sources.
4. Attach the local E-bus or K-bus terminals directly to the right-hand bus interface of the CPU module.
5. Connect the 24 V DC power supply lines to the module terminal block, verifying correct potential and grounding connection to the DIN rail.
6. Connect necessary field bus cables, Ethernet lines, and peripheral cables. Ensure proper shielding for communication cables to prevent electromagnetic interference.
