The Beckhoff KL3464 is a compact 4-channel analog input Bus Terminal designed for precise and efficient voltage measurement in industrial automation systems. Supporting 0…10 V single-ended signals, this module provides a cost-effective solution for acquiring analog values from sensors, transducers, and other field devices that generate voltage outputs.

Each of the four input channels allows direct connection of field signals, enabling engineers to capture multiple process values within a single terminal. The 0…10 V input range is a widely adopted standard, ensuring compatibility with numerous analog devices across diverse applications such as process control, building automation, and machine monitoring. By combining four channels into one compact module, the KL3464 simplifies wiring, reduces hardware requirements, and conserves valuable DIN rail space.

The terminal delivers precise and reliable measurements with its 12-bit resolution and a typical measurement uncertainty of less than ±0.3% relative to the full-scale value. This level of accuracy provides confidence in system performance, ensuring that control loops, monitoring tasks, and process optimisations are based on dependable data.

Fast signal acquisition is another strength of the KL3464. With a conversion time of approximately 2 ms per channel, it offers responsive updates suitable for applications that require near real-time measurement and control. This makes it particularly valuable for dynamic systems such as packaging machinery, dosing processes, or closed-loop regulation tasks.

The module features a high internal resistance of greater than 130 kΩ, minimising loading effects on the measured circuits. This ensures that connecting the KL3464 does not interfere with or distort the signals being measured, preserving signal integrity even when working with sensitive or low-power sensors.

Electrical safety and system stability are enhanced through 500 V electrical isolation between the K-bus and the signal voltage. This isolation protects both the terminal and the control system from potential cross-interference or damage, particularly important in environments where mixed-signal levels or noise are present.

The KL3464 is powered directly from the K-bus, drawing a typical 100 mA, which eliminates the need for additional external power supplies. This simplifies installation and ensures seamless integration into Beckhoff’s modular I/O system. As with other terminals in the Bus Terminal family, it can be combined with digital, analog, and specialty modules to build tailored system configurations for any automation project.

In summary, the Beckhoff KL3464 is a reliable and space-efficient analog input terminal offering four single-ended 0…10 V channels with high resolution, fast conversion, and excellent accuracy. With its 12-bit precision, short 2 ms conversion time, and robust electrical isolation, it is ideally suited for capturing process values in industrial, building, and machine automation. Compact, accurate, and easy to integrate, the KL3464 provides the essential functionality for dependable analog signal acquisition in modern control systems.
