The Beckhoff KL2488 Bus Terminal is a compact and versatile digital output module designed to provide high-density signal control in industrial automation systems. With eight independent output channels, each rated for 24 V DC and 0.5 A, the KL2488 enables efficient actuation of a wide variety of loads, from small relays and indicators to inductive devices and lamp loads.

By consolidating eight outputs into a single terminal, the KL2488 helps optimise control cabinet space while reducing hardware costs. This high channel density is especially advantageous in applications where numerous output signals are required, such as packaging machines, assembly lines, or building automation systems.

The module is engineered for ground switching operation, using 1-wire connection technology to simplify wiring while maintaining robust electrical performance. Each channel supports loads up to 0.5 A and is designed to handle ohmic, inductive, and lamp loads reliably. The inclusion of short-circuit protection ensures safe operation, with a maximum short-circuit current of less than 7 A per channel, protecting both the module and connected devices from damage.

In addition to current limitation, the KL2488 is designed to safely dissipate switching energy, with a breaking energy rating of less than 100 mJ per channel. This feature is particularly important when controlling inductive loads such as solenoids or small motors, as it ensures reliable and durable operation even in demanding applications.

Operating at a nominal voltage of 24 V DC (-15%/+20%), the KL2488 is fully compatible with standard industrial power supplies, making it easy to integrate into existing systems. Its design allows for consistent performance across a wide voltage range, ensuring stable output behaviour even in environments with slight voltage fluctuations.

The KL2488 integrates seamlessly into Beckhoff’s Bus Terminal I/O system, enabling it to be combined with a wide range of digital, analog, and specialty terminals to create flexible and scalable control architectures. Its modular design makes it ideal for distributed control systems, allowing engineers to tailor I/O capacity to the specific needs of each machine or installation.

In practical applications, the KL2488 is suited for switching indicator lamps, operating contactors, controlling relays, or driving smaller actuators. Its balance of high output density, robust protection features, and reliable performance makes it a cost-effective solution for projects where efficient space usage and dependable signal switching are priorities.

In summary, the Beckhoff KL2488 Bus Terminal delivers eight reliable digital outputs in a compact form factor. With its robust protection, compatibility with diverse load types, and efficient wiring technology, it provides a versatile and dependable solution for modern automation systems requiring high-density digital output control.
