BECKHOFF KL9400 Power Supply Unit Terminal

Description

The KL9400 is a power supply unit terminal designed for the K-bus, serving as a critical component in Beckhoff Bus Terminal systems. This module provides a regulated 5 V DC supply to the internal K-bus electronics, ensuring stable operation for connected I/O terminals. It is engineered to accept a 24 V DC input with an operating range of -15 % to +20 %. The KL9400 features integrated power contacts capable of handling up to 24 V DC at 10 A, allowing for efficient power distribution across the terminal block. This unit is fully short-circuit proof, enhancing the overall safety and reliability of the automation node.

Technical Specifications

Installation Guidelines

• Mounting: Ensure the KL9400 is snapped securely onto the standard DIN rail. The variable installation position allows for flexible arrangement within the control cabinet.
• Wiring: Utilize the pluggable wiring system provided by the KSxxxx series for easy maintenance. Ensure all power contact connections are tightened to specified torque requirements.
• Power Distribution: Verify that the total K-bus current draw does not exceed the 2 A output limit of this terminal. If the demand is higher, distribute additional KL9400 units as needed.
• Environment: While the unit is robust, ensure it is installed in an environment compliant with IP20 ratings, protecting it from liquid ingress and heavy dust accumulation.
• Hazardous Areas: When used in applications requiring Ex markings (II 3 G Ex nA IIC T4 Gc), ensure all installation procedures strictly follow local explosion protection regulations and safety protocols.
