KL5151 - Beckhoff Bus Terminals Position Measurement

The Beckhoff KL5151 Bus Terminals Position Measurement is a reliable module designed to handle incremental encoder signals for precise motion control applications. With support for a 24 V DC incremental encoder interface compliant with EN 61131-2 type 1, it accurately detects “0” signals at less than 5 V and “1” signals above 15 V, with a typical current draw of 5 mA per channel. The module offers one encoder channel and provides 2 x 32-bit input/output data along with 2 x 8-bit control/status signals in the process image, enabling smooth integration into automation systems that require high-resolution position feedback.

Built with a compact polycarbonate housing measuring 12 x 100 x 68 mm, the KL5151 is lightweight at approximately 50 g while maintaining durability for industrial use. It is mounted on a 35 mm DIN rail with a secure locking mechanism and allows side-by-side installation using Beckhoff’s double slot and key connection system. The terminal features signal LEDs for clear channel status indication, while its wiring system supports solid, flexible, and ferrule conductors with cross-sections from 0.08 to 2.5 mm². With a K-bus current consumption of 40 mA, the KL5151 is efficient and well-suited for integration into large I/O networks. Certified by CE, UL, CCC, ATEX, and IECEx and conforming to vibration and EMC standards, it delivers proven reliability in industrial environments.

In real-world use, the KL5151 Bus Terminals Position Measurement plays a key role in monitoring encoders for CNC machines, conveyor tracking, packaging automation, and robotics. Its accurate position measurement supports applications where precise motion feedback is essential for safety and efficiency. OEMs and system integrators value its compact design for panel space optimization, while maintenance engineers appreciate the easy wiring and dependable performance. Educational institutes also adopt it in training systems to help students learn position measurement and motion control concepts. With its combination of precision, certified reliability, and long service life, the Beckhoff KL5151 is a trusted choice for industries seeking advanced Bus Terminals Position Measurement solutions.
