The Beckhoff KL2541 is a powerful 1-channel motion control Bus Terminal designed for the direct operation of stepper motors in industrial automation. Compact and versatile, it integrates motor control, encoder feedback, and end-position monitoring into a single module, making it an ideal solution for precise, decentralised motion applications within Beckhoff’s modular I/O system.

Supporting stepper motors up to 48 V DC and 5 A, the KL2541 delivers strong performance for a wide range of motion tasks. Its ability to achieve step frequencies of up to 125,000 steps per second enables highly dynamic and responsive motor control, which is critical in applications requiring fast positioning, short cycle times, and accurate synchronization.

Direct motor connection simplifies wiring, reducing the need for external components. The terminal provides one output channel for the stepper motor along with dedicated inputs for an incremental encoder and two end-position sensors. This integrated design enables closed-loop monitoring of motor position, ensuring reliable motion sequences and safeguarding against overtravel.

The encoder input supports precise feedback, allowing the KL2541 to verify motor movements and detect discrepancies between commanded and actual positions. Combined with the two configurable end-position inputs, the terminal provides both safety and accuracy, helping to protect machinery while maintaining consistent process quality.

Power is supplied through two separate paths: a 24 V DC supply (via power contacts) for electronics, and an external motor supply ranging from 8…48 V DC. This design allows flexible adaptation to different motor types and system requirements, while the maximum 5 A output current ensures sufficient torque delivery for many mid-range stepper motor applications.

As part of Beckhoff’s Bus Terminal platform, the KL2541 integrates seamlessly with the K-bus, enabling direct communication with a higher-level controller such as a Bus Coupler or Embedded PC. Motor commands and feedback are exchanged in real time, ensuring smooth operation and coordination with other automation functions. Its compact housing saves valuable DIN rail space, reducing control cabinet size while maintaining full functionality.

The KL2541 is well suited for diverse applications including pick-and-place systems, lab automation, material handling, and packaging equipment. Its high step frequency and precise feedback capabilities make it particularly effective in systems where repeatability and responsiveness are essential.

In summary, the Beckhoff KL2541 is a robust and flexible motion interface terminal that combines stepper motor control, encoder feedback, and end-position monitoring in one compact device. With support for up to 48 V DC, 5 A output current, and step frequencies of 125,000 steps/s, it offers the performance required for demanding motion tasks. By integrating seamlessly into Beckhoff’s modular I/O system, the KL2541 delivers efficient, scalable, and precise motion control for modern automation environments.
