Product Details：

Product Dimensions：

The CX1100-0910 serves as the primary connection point between the external $24 \text{ VDC}$ power source and the CX-series Embedded PC CPU module. It is mounted on a standard $35 \text{ mm}$ DIN rail and connects to the CPU via a high-speed internal PC/104 bus. Beyond just providing power, this module acts as a gateway for Beckhoff Bus Terminals (KL series), allowing the CPU to communicate with a wide array of digital and analog I/O. The integrated capacitive UPS is a "maintenance-free" solution, as it does not rely on traditional lead-acid batteries that degrade over time, making it ideal for remote or hard-to-access installations.

Product Parameters

Input Voltage: $24 \text{ VDC}$ ( $-15\% / +20\%$ ).
Output Current: Maximum $3.5 \text{ A}$ for the internal bus.
UPS Type: Capacitive (Ultra-capacitors), maintenance-free.
UPS Buffer Time: Typically sufficient to back up the SRAM or perform a "Safe Shutdown" of the Windows CE or TwinCAT runtime (specific time depends on the CPU load).
I/O Interface: Supports the K-bus for standard Beckhoff Bus Terminals.
Display: $2 \times 16$ character FSTN LCD display with backlight for system diagnostics.
Control Keys: 4-way navigation switch (joystick-style) for interacting with the display menu.
Dimensions: $58 \text{ mm} \times 100 \text{ mm} \times 91 \text{ mm}$ .
Weight: Approximately $425 \text{ g}$ .

Product Advantages

A primary advantage of the CX1100-0910 is its Battery-Free UPS Design. Because it uses capacitors rather than batteries, it has a significantly longer service life and can operate in wider temperature ranges without the risk of battery leakage or capacity loss. The Integrated Diagnostic Display is another major benefit, allowing technicians to view IP addresses, system status, and error codes directly on the hardware without needing a laptop.

Additionally, the Seamless System Integration allows the power supply to report its status (such as "Power Fail" or "Charging") directly to the TwinCAT PLC software. This enables the programmer to write specific logic that triggers only when the system is running on backup power, ensuring that all data is written to the CompactFlash card securely before the energy is exhausted.

Important Considerations and Precautions

When installing the CX1100-0910, users must ensure the Total Current Consumption of all attached Bus Terminals does not exceed the $3.5 \text{ A}$ limit of the K-bus power contacts. If the I/O requirements are higher, additional power feed terminals (such as the KL9100) must be used. Grounding and Shielding are critical; the DIN rail must be properly earthed to ensure the EMC protection of the module functions correctly.

Regarding the UPS, users must remember that the Capacitor Charging Time is required after the first power-up before the UPS is fully functional. If power is lost immediately after a cold start, the buffer may not be sufficient. Furthermore, the UPS is intended for Data Preservation, not for continuing machine operations. The machine’s actuators and motors will lose power, and the UPS only keeps the "brain" (the CPU) alive long enough to finish its housekeeping tasks.

Product Applications

The CX1100-0910 is widely used in mission-critical automation where data loss is unacceptable.

Wind Turbine Control: Providing power and K-bus I/O interface for turbines where power fluctuations are common and maintenance-free components are required.
Building Automation: Managing HVAC and lighting systems where the LCD display allows facility managers to check system health quickly.
Machine Tooling: Ensuring that the current position of a CNC axis is saved to retentive memory during an unexpected power outage.
Semiconductor Manufacturing: Protecting sensitive process data and ensuring a clean software shutdown to prevent corruption of the operating system on the CompactFlash card.
Remote Pump Stations: Operating in environments with extreme temperatures where traditional UPS batteries would fail prematurely.
