The Beckhoff KL4408 Bus Terminal is a compact, multi-channel analogue output module designed to provide reliable voltage signals for process control, machine automation, and monitoring applications. With eight single-ended output channels, the terminal offers high channel density in a slim format, making it ideal for projects that require multiple analogue outputs without consuming extensive cabinet space.

Each channel delivers an output voltage in the range of 0…10 V, covering a broad spectrum of industrial applications such as controlling proportional valves, analogue actuators, signal transmitters, and test equipment. By centralising eight outputs in a single terminal, the KL4408 reduces wiring effort, simplifies installation, and supports cost-effective system expansion.

Engineered for precision, the module provides 12-bit resolution, ensuring fine signal granularity for accurate analogue control. With a conversion time of approximately 8 ms, it generates stable outputs while maintaining responsiveness in most automation tasks. Furthermore, its output error of less than ±0.2% relative to the end value guarantees reliable accuracy, making the KL4408 suitable for both standard automation tasks and applications with higher performance requirements.

Robustness is built into the design. Each output can handle loads greater than 5 kΩ and is short-circuit proof, safeguarding both the terminal and connected devices against damage. This feature enhances system reliability and reduces downtime, particularly in demanding industrial environments where equipment protection is essential.

As part of the Beckhoff Bus Terminal system, the KL4408 integrates seamlessly into distributed control architectures. It is powered via the K-bus, which supplies the logic signals, while the analogue output voltages are generated from the connected 24 V supply. The modular format allows easy combination with other I/O terminals to create tailored solutions for specific automation needs.

When paired with Beckhoff’s TwinCAT automation software, the KL4408 offers straightforward configuration, monitoring, and diagnostic functions. Engineers can parameterise output channels, integrate them into control loops, and monitor their performance in real time. This integration reduces engineering time, improves transparency, and enhances overall system maintainability.

The KL4408 is particularly well-suited to process automation, building automation, test stands, and machine control systems, where multiple analogue signals must be generated with consistent accuracy. Its combination of precision, robustness, and high channel density makes it an efficient solution for engineers seeking to streamline analogue signal generation in distributed I/O systems.

In summary, the Beckhoff KL4408 Bus Terminal delivers reliable, high-density analogue output capability with 12-bit precision, robust safety features, and seamless integration into Beckhoff’s modular automation platform. Its accuracy, flexibility, and compact design make it a dependable choice for a wide range of analogue control tasks in modern industrial automation.
