The Beckhoff CX1100-0002 is a power supply and I/O interface module designed for use with the Beckhoff CX1010 and CX1020 Embedded PCs. Now in its service phase, the CX1100-0002 remains an important component for legacy systems, providing reliable power distribution, I/O interfacing, and system monitoring within compact industrial automation setups.

At its core, the CX1100-0002 operates with a 24 V DC input, offering a tolerance of -15%/+20% to ensure resilience against fluctuations in industrial power supplies. It delivers up to 1.75 A current for the K-bus, supporting reliable communication and operation of Beckhoff K-bus I/O terminals. This makes it a dependable backbone for control architectures built around the CX1010/CX1020 series, maintaining system integrity and stable operation in day-to-day use.

The inclusion of 8 kB NOVRAM provides secure, non-volatile data storage. This feature safeguards essential process data and system states during unexpected power losses, allowing systems to recover without data corruption or loss of critical information. By preserving vital runtime data, the NOVRAM ensures consistent system behaviour and enhances reliability across automation applications.

The CX1100-0002 also integrates an illuminated FSTN display with two lines of 16 characters each, providing operators with immediate access to system information and diagnostic messages. This built-in display enables quick system checks directly on the device, reducing the need for external diagnostic equipment and supporting faster troubleshooting in the field.

In addition, the module features diagnostic LEDs that provide at-a-glance confirmation of system conditions. Indicators for PWR (power), I/O Run, and I/O Error make it easy for operators and maintenance staff to monitor status, quickly detect issues, and take corrective action.

With a maximum power consumption of just 3.5 W, the CX1100-0002 is efficient and economical to operate, supporting energy-conscious industrial environments. Its compact dimensions (40 mm x 100 mm x 91 mm) make it easy to integrate into space-limited control cabinets while still delivering essential functionality.

The CX1100-0002’s robust design and modular approach align with Beckhoff’s long-standing commitment to flexible, scalable automation solutions. By serving as both the power supply and K-bus I/O interface, it reduces system complexity while ensuring consistent performance across the embedded PC platform.

In practice, this module is ideal for maintaining reliable operation in legacy Beckhoff automation systems. It supports both power distribution and data handling, making it an essential component for users who continue to rely on the proven CX1010 and CX1020 systems.

In summary, the Beckhoff CX1100-0002 combines stable power supply, reliable I/O interfacing, integrated data protection, and user-friendly diagnostics in a compact, efficient design. Even in its service phase, it continues to provide dependable functionality for automation systems based on the CX1010 and CX1020 platforms.
