The Beckhoff KL8548 is an advanced 8-channel analogue output module designed to deliver precise voltage control in automation environments. With its compact design and multifunctional capabilities, it is ideal for applications requiring multiple analogue outputs for actuators, control devices, or simulation tasks.

The module provides eight voltage outputs within the 0…10 V range, making it suitable for controlling a variety of analogue devices such as valve actuators, transducers, frequency inverters, and other process equipment. Each channel is generated with a 12-bit resolution, enabling fine granularity and reliable signal reproduction for smooth and accurate control.

In addition to its outputs, the KL8548 is equipped with eight potentiometer inputs, which can be used for manual adjustments, calibration, or as reference signals for testing. This dual functionality increases flexibility in laboratory and industrial applications, allowing engineers to adjust settings directly without requiring additional external modules.

The module operates from a 24 V DC nominal supply (-15%/+20%) and offers two selectable consumption modes: ECO mode, where K-bus current draw is reduced to 50 mA, and full-scale mode, which consumes 95 mA. This dual-mode approach provides engineers with the option to balance energy efficiency against maximum output stability, depending on the application’s needs.

As part of Beckhoff’s Bus Terminal system, the KL8548 integrates seamlessly with the K-bus, which supplies communication and system power. This allows it to connect directly to other digital, analogue, and specialty terminals, forming scalable and modular I/O stations. Its DIN rail mounting and compact housing reduce cabinet space requirements, making it suitable for both centralised and decentralised installations.

By pairing with TwinCAT automation software, the KL8548 supports straightforward configuration, mapping, and diagnostics. Engineers can easily assign outputs, monitor performance, and perform troubleshooting within a unified software environment, ensuring transparency and simplifying maintenance.

The KL8548 is particularly useful in applications requiring multi-channel analogue control, such as process automation, building management systems, laboratory setups, and test benches. Its ability to handle both fine analogue signal generation and manual adjustment inputs makes it versatile for development environments as well as operational control systems.

In summary, the Beckhoff KL8548 Bus Terminal offers a compact and flexible solution for analogue signal generation. With 8 outputs, ±10 V range, 12-bit resolution, dual consumption modes, and integrated potentiometer inputs, it provides engineers with precision, efficiency, and reliability for controlling analogue devices in modern automation systems.
