The Beckhoff KL1418 is an 8-channel digital input Bus Terminal designed for high-speed signal acquisition in 24 V DC automation environments. With its ultra-fast input filter and efficient design, the KL1418 is a reliable solution for capturing rapid control signals from sensors, switches, and other field devices in demanding industrial applications.

Each of the eight input channels is designed for 24 V DC operation, accommodating a tolerance range of –15% to +20%. The terminal is fully compliant with EN 61131-2 type 1/3 specifications, ensuring compatibility with a wide variety of industrial sensors and actuators. This adherence to international standards makes the KL1418 a dependable choice for consistent performance in machine control, process automation, and building systems.

A standout feature of the KL1418 is its speed. With an integrated input filter that provides a typical delay of just 0.2 ms, the terminal can capture and process signals at very high speeds. This makes it particularly well suited for applications such as high-speed machine cycles, fast-switching sensors, or motion-related signals where rapid detection is critical to system accuracy and performance.

The input channels are designed to operate with a typical current of 3 mA, following EN 61131-2 type 3 specifications. This ensures low loading on connected sensors, supporting compatibility with both standard and low-power field devices. Despite its fast performance, the KL1418 maintains energy efficiency, consuming only about 5 mA from the K-bus and approximately 2 mA plus load from the power contacts. This low power demand supports scalability, allowing larger assemblies of terminals without overburdening the system’s power budget.

Connection is simplified by the terminal’s 1-wire technology, enabling straightforward wiring for each input channel. This design reduces installation effort and ensures reliable connectivity, particularly in high-density configurations where space is limited.

As part of Beckhoff’s modular Bus Terminal system, the KL1418 integrates seamlessly into existing I/O assemblies. It communicates input states directly via the K-bus to the higher-level controller, ensuring real-time responsiveness in automation tasks. Its compact housing conserves DIN rail space, making it ideal for installations where multiple high-speed input channels must be consolidated in a limited area.

In summary, the Beckhoff KL1418 is a high-performance digital input terminal that combines speed, efficiency, and reliability. With eight 24 V DC input channels, a fast 0.2 ms input filter, compliance with EN 61131-2 standards, and low power consumption, it is ideally suited for applications requiring rapid and accurate signal capture. Whether applied in packaging machinery, robotics, process control, or building automation, the KL1418 ensures dependable high-speed digital input acquisition in a compact and scalable format.
