The Beckhoff KL1819 Bus Terminal is a high-density digital input module designed to efficiently capture multiple 24 V DC signals in compact automation systems. Offering 16 independent input channels, it provides a space-saving solution for connecting a large number of digital devices, such as sensors, switches, or push buttons, within a single terminal. Its compact design and ease of integration make it an ideal choice for control cabinets where efficiency, reliability, and performance are critical.

Each input of the KL1819 complies with EN 61131-2, type 1/3 specifications, ensuring broad compatibility with industrial control signals. With a typical input current of 3 mA (type 3), it allows reliable detection of signal states while maintaining energy efficiency. This makes the terminal versatile enough to handle a wide range of industrial sensors and input devices.

A standout feature of the KL1819 is its fast input filter, which provides a typical response time of just 0.2 ms. This rapid signal acquisition is particularly valuable in applications where high-speed response is essential, such as packaging machinery, material handling, or process automation systems with time-sensitive operations. The short delay ensures accurate and immediate detection of changes in input states, improving the responsiveness of the entire control system.

For operational safety and robustness, the terminal incorporates 500 V electrical isolation between the K-bus and the field potential. This protective barrier ensures reliable signal transmission while safeguarding the system against electrical disturbances, interference, or faults. It enhances both durability and system stability in environments with mixed signal or power levels.

The KL1819 integrates seamlessly into Beckhoff’s modular Bus Terminal system. It maps its 16 inputs directly into the process image, making data readily accessible to the control system. With no address or configuration settings required, the terminal operates as a true plug-and-play device, minimising commissioning time and simplifying system design. This feature is especially useful in large-scale systems where rapid deployment and straightforward scalability are important.

Designed for practicality, the KL1819 employs 1-wire connection technology, simplifying wiring and reducing installation effort. By consolidating 16 inputs into a single terminal, it significantly reduces space requirements within the control cabinet, while still providing high functionality and performance.

The KL1819 is ideally suited for a wide variety of applications, including factory automation, machine building, and process industries where reliable, high-speed digital input collection is needed. It supports engineers in building compact, efficient, and scalable automation systems that meet modern industrial demands.

In summary, the Beckhoff KL1819 Bus Terminal offers a compact, efficient, and high-performance solution for digital input acquisition. With its 16 input channels, fast 0.2 ms response, strong electrical isolation, and easy plug-and-play integration, it provides a reliable foundation for advanced automation systems.
