The Beckhoff KL4404 is a 4-channel analog output Bus Terminal engineered for generating precise voltage signals in automation systems. Delivering single-ended 0…10 V outputs, the KL4404 is a reliable solution for driving actuators, setpoints, and control devices in industrial and building automation environments.

Each of the four channels operates independently, allowing the KL4404 to provide flexible voltage control across multiple devices within a single module. Supporting the widely adopted 0…10 V standard, it ensures compatibility with a broad range of actuators, drives, and monitoring equipment. This makes it especially useful in process automation, HVAC control, machine tools, and any application where accurate analog voltage signals are required.

The module delivers strong precision with a 12-bit resolution, enabling finely graduated signal outputs that allow smooth and accurate control of field devices. With an output error margin of less than ±0.1% relative to the end value, the KL4404 guarantees high accuracy and reliability. This ensures stable operation even in applications where signal precision directly affects system performance and product quality.

The conversion time of approximately 4 ms further enhances its capability, enabling fast and responsive signal updates. This speed makes the KL4404 suitable for dynamic applications where real-time control is critical, such as packaging systems, dosing machines, or responsive process adjustments.

Durability is built into the design. The module’s outputs are short-circuit proof and support loads greater than 5 kΩ, protecting both the terminal and connected devices from damage caused by wiring errors or electrical faults. This robustness minimises downtime and ensures continuous operation in demanding industrial environments.

Electrical isolation rated at 500 V between the K-bus and the signal voltage provides an additional layer of safety. This isolation not only enhances operational reliability but also prevents interference and ensures system stability when working with sensitive equipment or mixed-signal environments.

As part of Beckhoff’s modular Bus Terminal system, the KL4404 integrates seamlessly with other I/O modules. Power and communication are supplied via the K-bus, allowing straightforward installation and easy system expansion. Its compact housing conserves DIN rail space, supporting high-density cabinet layouts and modular system scalability.

In addition to its technical strengths, the KL4404 improves efficiency by consolidating four analog outputs in one compact terminal. This reduces hardware costs, wiring effort, and installation time, making it an economical yet powerful solution for analog voltage signal generation.

In summary, the Beckhoff KL4404 Bus Terminal is a precise, robust, and compact analog output module. Offering four single-ended 0…10 V channels, 12-bit resolution, fast conversion, and robust electrical isolation, it provides reliable performance for a wide range of automation applications. Whether used for setpoint generation, actuator control, or monitoring tasks, the KL4404 ensures accurate and dependable voltage output in modern industrial systems.
