The Beckhoff KL9190 Potential Supply Terminal is a robust and versatile module designed to supply additional operating potential to a Bus Terminal block. Engineered for flexibility, it supports arbitrary supply voltages up to 230 V AC, making it a highly adaptable component for a wide range of automation and control applications.

With a current load capacity of up to 10 A, the KL9190 provides reliable power distribution to downstream terminals. This makes it suitable for supporting power-intensive configurations, ensuring stable operation even in systems with high consumption requirements. Its ability to handle both AC and DC voltages expands its versatility, allowing it to be used across diverse machine and process environments without requiring separate, specialised supply modules.

The KL9190 is designed with electrical isolation between the field potential and the K-bus, ensuring safe and reliable operation. This separation guarantees that the terminal’s infeed does not interfere with the communication bus, maintaining the integrity and stability of data transfer while safely delivering operating potential to connected terminals.

A key feature of the KL9190 is its renewed infeed capability, which allows it to reintroduce supply potential at any point in a terminal strand. This makes it invaluable in modular installations where different voltage groups must be defined or when long terminal strings exceed the power limits of a single infeed. By refreshing the supply, it ensures consistent voltage delivery and reduces the risk of voltage drops or instability.

The K-bus is looped through, meaning communication continuity is preserved regardless of how the KL9190 is positioned within the terminal string. This ensures that system designers can freely place the module where new supply potential is required, without interrupting bus communication or reconfiguring the process image.

Compact in design, the KL9190 has a housing width of only 12 mm and a weight of approximately 50 g, making it highly space-efficient for control cabinet layouts. Despite its slim profile, it delivers robust performance, ensuring long service life and dependable operation even under industrial conditions.

In practice, the KL9190 is widely used to divide Bus Terminal blocks into separate supply groups, such as isolating I/O sections that operate at different voltages or refreshing the supply for long strands. This modular flexibility makes it particularly valuable in machine building, process control, and building automation systems.

In summary, the Beckhoff KL9190 Potential Supply Terminal is a compact, powerful, and flexible solution for supplying additional voltage to Bus Terminal systems. With support for any voltage up to 230 V AC, 10 A current handling, electrical isolation, and renewed infeed capability, it enables safe, reliable, and efficient potential distribution in modular automation architectures.
