The Beckhoff KL2602 is a 2-channel relay output Bus Terminal designed to provide reliable switching of AC and DC loads within automation systems. With two make contacts and broad load compatibility, it offers a practical and flexible solution for controlling actuators, indicators, and other devices directly from the modular I/O platform.

Each channel of the KL2602 can switch voltages up to 230 V AC or 30 V DC, making it suitable for a wide range of industrial and building automation applications. This dual capability allows the terminal to bridge both AC and DC circuits, reducing the need for separate switching modules and enabling simplified system architectures.

The terminal is designed to handle a variety of load types, including ohmic, inductive, and lamp loads. For ohmic loads, such as resistive heaters or incandescent lamps, the KL2602 can switch up to 5 A AC/DC per channel. For inductive loads, including relays, solenoids, or motors, it supports switching currents up to 2 A AC/DC. This adaptability ensures the KL2602 is capable of meeting diverse application requirements, from straightforward power switching to controlling dynamic inductive devices.

Robust relay technology forms the core of the KL2602, providing galvanic isolation between the control side and the switched power circuits. This isolation enhances system safety and ensures stable operation, even in environments where electrical noise or ground potential differences may be present. The use of mechanical relays also allows for reliable switching of loads that may be unsuitable for semiconductor outputs, including certain inductive or capacitive devices.

The KL2602 integrates seamlessly into Beckhoff’s modular I/O system via the K-bus, which supplies control communication and power for electronics. Load power is provided directly to the relay contacts, ensuring independent handling of field voltages while maintaining full compatibility with other terminals in the system. This modularity supports scalable and flexible system design, allowing engineers to configure tailored I/O assemblies for specific applications.

In addition to its technical capabilities, the KL2602 is designed for compactness and efficiency. By combining two relay outputs in a single module, it reduces DIN rail usage, wiring effort, and overall system cost. This makes it particularly advantageous for installations where space is at a premium or where multiple switching points must be consolidated into one compact solution.

In summary, the Beckhoff KL2602 is a robust and versatile relay output terminal offering two channels for switching AC and DC loads. With support for voltages up to 230 V AC or 30 V DC, current capacities of 5 A (ohmic) and 2 A (inductive), and compatibility with a wide range of load types, it provides a reliable and flexible solution for modern automation. Compact, safe, and seamlessly integrated into the Bus Terminal platform, the KL2602 is ideally suited for switching tasks in industrial and building environments alike.
