The Beckhoff KL2012 is a 2-channel digital output Bus Terminal designed to switch 24 V DC actuators and loads in automation systems. Compact, reliable, and versatile, it provides a robust solution for controlling a wide range of devices such as relays, solenoids, contactors, and indicator lamps directly from Beckhoff’s modular I/O system.

Each of the two output channels is capable of supplying up to 0.5 A, making the KL2012 suitable for small and medium loads. The terminal is engineered to support ohmic, inductive, and lamp loads, providing flexibility for use across diverse applications. Whether powering control signals, actuators, or visual indicators, the KL2012 delivers dependable switching performance.

Protection features are built into the terminal to ensure durability and system safety. The outputs are short-circuit proof, with the short-circuit current limited to less than 2 A per channel. Additionally, the breaking energy is restricted to below 150 mJ per channel, which safeguards both the terminal and connected devices during switching operations. These protective functions minimise downtime and reduce the risk of damage due to overloads or wiring errors.

Electrical safety is enhanced through 500 V isolation between the K-bus and the field potential. This isolation ensures that disturbances from the field side do not affect the control system, improving reliability in industrial environments where electrical noise or voltage fluctuations may be present.

Power consumption is efficient, with the terminal typically drawing only 15 mA from the power contacts in addition to the load current. This low consumption supports scalability, allowing many KL2012 modules to be deployed within a single system without overloading the power distribution.

The KL2012 integrates seamlessly into Beckhoff’s modular I/O architecture. Communication with the higher-level controller is managed via the K-bus, enabling real-time switching commands and feedback. Its compact housing conserves DIN rail space, making it well suited for high-density installations where multiple outputs are required in a limited area.

Applications for the KL2012 span a wide range of automation environments. In machine control, it can be used to switch valves, relays, or pilot lamps. In building automation, it can control lighting, shutters, or low-voltage actuators. Its robustness and protective features make it equally reliable in manufacturing, process automation, or material handling systems.

In summary, the Beckhoff KL2012 is a versatile and compact 2-channel digital output terminal designed for switching 24 V DC loads up to 0.5 A per channel. With its short-circuit protection, controlled breaking energy, 500 V isolation, and compatibility with a wide range of loads, it ensures reliable and safe operation in demanding automation environments. Seamlessly integrated into Beckhoff’s Bus Terminal system, the KL2012 delivers dependable performance for a broad spectrum of industrial and building control applications.
