The Beckhoff KL3002 Bus Terminal is a compact and reliable analogue input module designed to deliver accurate and stable voltage measurements in distributed control and monitoring systems. With two independent differential inputs, the KL3002 provides engineers with a versatile solution for acquiring analogue signals from a wide variety of sensors and transducers.

Supporting an input range of –10 V to +10 V, the KL3002 can process signals from diverse industrial devices, including process sensors, position transducers, and control equipment. Its differential input technology is a key strength, as it improves signal integrity by effectively cancelling out common-mode interference. This makes the terminal especially valuable in noisy industrial environments, where long cable runs or electromagnetic disturbances could otherwise degrade measurement accuracy. The module’s ability to tolerate a common-mode voltage (UCM) of up to 35 V further enhances its robustness in challenging conditions.

With a 12-bit resolution, the KL3002 provides fine measurement granularity, allowing for detailed and precise signal conversion. Its conversion time of approximately 2 ms ensures responsive data acquisition, enabling automation systems to capture real-time process dynamics with minimal delay. The terminal’s high internal resistance (>200 kΩ) ensures that connected signal sources are not significantly loaded, preserving the accuracy of measurements across all channels.

The KL3002 is powered directly via the K-bus, simplifying wiring and eliminating the need for a separate power source. As part of Beckhoff’s modular Bus Terminal system, it integrates seamlessly with other terminals, enabling customised and scalable I/O configurations. This modularity makes the KL3002 suitable for both small-scale machine controls and large distributed automation networks.

In addition to its hardware strengths, the KL3002 integrates smoothly with Beckhoff’s TwinCAT automation software, allowing users to configure, monitor, and analyse analogue signals within a unified engineering environment. This combination of hardware and software support provides a comprehensive platform for implementing control strategies, data logging, and diagnostics.

Typical applications for the KL3002 include process monitoring, machine control, and industrial automation tasks requiring accurate analogue input. Whether measuring voltages in laboratory setups, capturing process variables in manufacturing, or feeding feedback signals into closed-loop control systems, the KL3002 ensures stable and dependable performance.

In summary, the Beckhoff KL3002 Bus Terminal delivers precise, noise-resistant, and flexible analogue input capabilities in a compact form factor. With its differential design, robust ±10 V input range, high resolution, and seamless K-bus integration, it is an ideal choice for engineers seeking reliable signal acquisition in demanding industrial environments.
