The Beckhoff KL3202 Bus Terminal is a versatile and accurate analogue input module for acquiring temperature values using RTD sensors. Featuring two independent input channels, the KL3202 is designed for applications that demand reliable monitoring and control of thermal processes in automation, manufacturing, and process industries.

The terminal is compatible with a wide range of resistance temperature detectors, including Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, and Ni1000 sensors. Beyond standard RTD measurement, the KL3202 can also be used for resistance measurements such as potentiometers within the 10 Ω to 1.2/5 kΩ range, making it flexible for both temperature and resistance acquisition tasks. This versatility ensures its suitability for a broad variety of applications, from monitoring environmental conditions to controlling process equipment.

With a 16-bit resolution, the KL3202 delivers precise and detailed temperature measurements, enabling accurate process regulation and monitoring. It covers wide measurement ranges, from –200…+850°C for Pt sensors to –60…+250°C for Ni sensors, ensuring applicability in everything from low-temperature refrigeration monitoring to high-temperature industrial environments.

The terminal supports both 2-wire and 3-wire connection methods, with the 3-wire option set as default to help compensate for lead resistance, thereby improving measurement accuracy. This flexibility allows engineers to adapt wiring configurations depending on installation requirements and sensor cabling lengths.

The KL3202 operates with a conversion time of approximately 250 ms, balancing stable and accurate readings with practical update intervals. This makes it suitable for applications where precise but not ultra-fast measurements are required, such as climate monitoring, heating and cooling control, or steady-state process environments.

Powered directly from the K-bus, the KL3202 integrates seamlessly into Beckhoff’s modular Bus Terminal system. Its compact and modular design reduces cabinet space requirements while supporting easy system expansion. By combining the KL3202 with other digital or analogue terminals, engineers can build customised and scalable I/O solutions tailored to specific automation tasks.

Practicality is further enhanced by the KL3202’s straightforward configuration and compatibility with TwinCAT software, which allows engineers to parameterise sensor types and monitor system performance efficiently. The terminal’s robust design and wide measuring ranges make it a dependable choice for industrial environments where temperature control and reliability are critical.

In summary, the Beckhoff KL3202 Bus Terminal is a precise, adaptable, and reliable solution for RTD temperature measurement. With two input channels, wide sensor compatibility, flexible wiring methods, and seamless K-bus integration, it provides engineers with the tools to achieve accurate and scalable temperature monitoring in a wide variety of industrial automation settings.
