Beckhoff KL9010 Terminal Base for E-bus Couplers | 1-Channel Power Supply

The Beckhoff KL9010 is a fundamental component of the Beckhoff Bus Terminal (BT) system. It serves as the 1-channel power feed terminal that supplies the 24 V DC operating voltage to the entire Bus Terminal block. Mounted directly to the left of the Bus Coupler (e.g., BK series), the KL9010 is the essential first terminal that powers the subsequent I/O modules. Its compact design, secure screw connection, and reliable performance make it a mandatory starting point for thousands of automation installations worldwide.

Detailed Technical Description:

The Beckhoff KL9010 Terminal Base is the designated power injection point for the Beckhoff modular I/O system. Unlike the signal terminals that handle digital or analog data, the KL9010 is responsible for distributing the 24 V DC field power to the electronic assemblies of all the following Bus Terminals in the station.

Key Functionality:

• Centralized Power Distribution: It accepts the 24 V DC supply via a robust screw-clamp connection and distributes it across the E-bus power rail to all subsequent modules in the block.

• Mandatory Placement: The KL9010 must always be the first terminal base directly adjacent to the Bus Coupler. A Bus Terminal station cannot function without it.

• Electrical Isolation: It features electrical isolation between the power supply electronics and the fieldbus (K-bus), protecting the sensitive control side from disturbances on the power side.

This terminal is a simple, yet critical, component for building a reliable and scalable Beckhoff I/O system.
