The Beckhoff CX1100-0004 is a combined power supply and I/O interface module specifically designed for use with the Beckhoff CX1010 and CX1020 Embedded PCs. Now in its service phase, it remains an important component in many established Beckhoff automation systems, providing stable power delivery, reliable I/O integration, and user-friendly diagnostics in a compact format.

The unit operates with a 24 V DC input and supports an input tolerance of -15% to +20%, ensuring resilience in industrial environments where voltage fluctuations may occur. It delivers up to 2 A current for the E-bus, supplying sufficient power for connected I/O terminals and enabling stable communication between the CPU and the I/O modules. This makes it well suited for distributed control architectures where dependable data exchange and power consistency are essential.

The CX1100-0004 includes 8 kB of NOVRAM, a non-volatile memory resource that safeguards critical process data and system states during unexpected power failures. By securely storing runtime data, NOVRAM ensures that the system can recover seamlessly when power is restored, reducing downtime and preventing data loss.

For user interaction and monitoring, the module integrates a two-line, 16-character FSTN display with backlighting. This illuminated display provides clear, real-time system information and diagnostic messages, enabling operators and engineers to perform quick checks directly on the device. Complementing the display, the front panel includes diagnostic LEDs for power (PWR), link/activity (L/A), and run (RUN), giving at-a-glance feedback on operating status and simplifying troubleshooting.

Connection to the system is facilitated by spring-loaded terminals (adapter terminal technique), which provide secure, vibration-resistant wiring while also enabling quick and easy installation. This design minimises wiring errors, enhances reliability, and reduces installation time, which is particularly important in fast-paced industrial environments.

With a maximum power consumption of just 3.5 W, the CX1100-0004 is energy-efficient, supporting the sustainability goals of modern industrial facilities while maintaining robust functionality. Its compact dimensions and modular design allow it to integrate easily into control cabinets without occupying excessive space.

As part of Beckhoff’s modular embedded PC ecosystem, the CX1100-0004 serves a critical role in ensuring power stability, reliable I/O interfacing, and data protection. Even though it is now in its service phase, it continues to provide dependable functionality for legacy systems built around the CX1010 and CX1020 platforms.

In summary, the Beckhoff CX1100-0004 combines stable 24 V DC power delivery, reliable E-bus communication, integrated data protection, and intuitive diagnostics in a compact design. It remains a trusted solution for maintaining legacy Beckhoff embedded PC systems, ensuring long-term reliability and operational efficiency.
