The Beckhoff KL4004 is a 4-channel analog output Bus Terminal designed to provide precise voltage signals for industrial automation systems. With its ability to generate four independent 0…10 V outputs, the KL4004 offers a compact, reliable, and efficient solution for driving actuators, control devices, and other equipment that require accurate voltage-based control signals.

Each of the four outputs delivers a signal in the 0…10 V range, which is widely used across industrial and building automation applications. The module’s differential output technology ensures reliable signal integrity, even in environments subject to electrical noise or interference. This makes the KL4004 particularly suitable for applications such as process control, setpoint adjustment, and driving proportional actuators or analog indicators.

One of the standout features of the KL4004 is its precision. With a 12-bit resolution, the terminal is capable of producing finely graduated output signals, enabling smooth and accurate control over connected devices. The output error of less than ±0.1% relative to the end value ensures consistently high accuracy, making it ideal for applications where precise voltage control directly impacts product quality or system performance.

The outputs are designed to be robust, supporting loads greater than 5 kΩ and featuring short-circuit protection. This safeguards the module and connected devices against accidental wiring errors or unexpected conditions, enhancing the reliability of the overall system. The combination of protection and high output performance ensures dependable operation in demanding industrial environments.

Power for the KL4004 is supplied directly through the K-bus, eliminating the need for additional external wiring and simplifying integration. As part of Beckhoff’s modular Bus Terminal system, the KL4004 fits neatly into existing configurations, providing scalable expansion options for analog output requirements. Its compact housing conserves valuable DIN rail space, making it a cost-effective solution for high-density control cabinet installations.

The KL4004 also enhances system flexibility. By offering four outputs in a single terminal, it reduces the need for multiple modules, lowering hardware costs and simplifying installation. Its ability to interface directly with the control system via the K-bus means output values can be adjusted in real time, supporting dynamic control strategies in applications such as packaging machines, HVAC systems, or production equipment.

In summary, the Beckhoff KL4004 is a versatile and precise analog output terminal that provides four independent 0…10 V voltage outputs. With its 12-bit resolution, low output error, short-circuit protection, and seamless integration into the Bus Terminal system, it is ideal for applications requiring reliable voltage control. Whether used in process automation, building management, or machine control, the KL4004 ensures accurate, dependable, and efficient analog signal generation in modern industrial systems.
