The Beckhoff KL3162 Bus Terminal is a high-precision analog input module designed for acquiring 0…10 V voltage signals with exceptional accuracy and stability. With two differential input channels and 16-bit resolution, the KL3162 is engineered for applications that demand reliable measurement performance, particularly in environments where precision and noise immunity are critical.

By using differential input technology, the KL3162 minimises the impact of electrical noise and interference, ensuring accurate signal acquisition even in electrically harsh industrial environments. This makes it ideal for scenarios involving long signal cables, sensitive measurement devices, or noisy production settings. The module tolerates common-mode voltages up to 10 V, further enhancing its robustness and versatility in practical applications.

Each input channel offers an internal resistance greater than 70 kΩ, ensuring minimal loading on connected sensors or devices. This high input impedance allows accurate signal acquisition without distorting the source measurement, making the KL3162 particularly suitable for integration with delicate instrumentation.

The terminal’s performance can be tailored through its configurable conversion times and filter settings. With a default conversion time of 140 ms, the KL3162 provides stable measurements suited for slowly varying process signals. However, engineers can adjust the conversion time for faster response when required. Similarly, the integrated 50 Hz filter helps suppress mains-related interference, ensuring accurate readings in environments where electrical noise could otherwise degrade performance.

Power for the terminal electronics is supplied via the K-bus, allowing seamless integration into Beckhoff’s modular Bus Terminal system. Its compact design makes it easy to combine with digital, analog, or communication modules, enabling flexible I/O configurations for both small and large automation systems.

The 16-bit resolution of the KL3162 ensures fine-grained signal acquisition, capturing subtle changes in measured values with high fidelity. This precision is critical in industries such as test and measurement, laboratory automation, machine control, and process monitoring, where accurate voltage acquisition underpins product quality and process reliability.

Practical applications include capturing analog voltage signals from sensors, transducers, and measuring devices. For example, in process automation it can monitor pressure or flow converters; in laboratory environments it can acquire precise experimental data; and in machine automation it can provide accurate feedback for closed-loop control systems.

In summary, the Beckhoff KL3162 Bus Terminal is a high-precision analog input module built for robust and accurate measurement of 0…10 V signals. With two differential channels, 16-bit resolution, configurable filters and conversion times, and strong noise immunity, it delivers reliable and flexible performance for applications demanding precise voltage acquisition in modern automation environments.
