The Beckhoff KL2134 is a 4-channel digital output Bus Terminal engineered for 24 V DC load switching in industrial automation systems. With its compact form factor and robust electrical protection features, the KL2134 delivers reliable performance while simplifying cabinet design and wiring in distributed control architectures.

Each of the four outputs is rated at 0.5 A, providing ample capacity for controlling actuators, relays, solenoids, lamps, or other 24 V DC devices. The outputs are short-circuit proof, with a maximum short-circuit current of < 2 A, ensuring that faults in connected loads do not damage the terminal. In addition, each channel has a breaking energy rating of < 150 mJ, making it well suited for inductive load switching while maintaining long-term reliability.

The KL2134 is built with reverse voltage protection, safeguarding against incorrect wiring or accidental polarity reversal. This feature enhances system safety and reduces the risk of equipment damage during installation or maintenance. Together with short-circuit protection, these safeguards make the terminal highly robust in demanding factory environments.

Supporting 2- and 3-wire connection technology, the KL2134 offers flexibility in system integration. Whether used in simple two-wire circuits or in three-wire setups with separate supply lines, the terminal accommodates a variety of wiring strategies, reducing installation effort and increasing application versatility.

Operating at a nominal voltage of 24 V DC (-15%/+20%), the KL2134 complies with industry-standard power ranges. Its compatibility with ohmic, inductive, and lamp loads allows engineers to use a single output module for a wide variety of devices, reducing the need for multiple specialised terminals.

With its compact Bus Terminal form factor, the KL2134 integrates seamlessly into Beckhoff’s modular I/O system. It connects directly with other KL terminals via the terminal bus, enabling scalable, space-efficient designs for automation systems. Configuration and diagnostics are managed through Beckhoff’s TwinCAT software, allowing for transparent monitoring of output states and rapid troubleshooting.

The combination of high reliability, built-in protection, and compact design makes the KL2134 suitable for many industries, including machine building, packaging, material handling, and building automation. Typical applications include driving indicator lamps, powering pneumatic valves, switching relays, and actuating small DC motors.

In summary, the Beckhoff KL2134 is a robust and versatile 4-channel digital output terminal for 24 V DC loads. With short-circuit proof outputs, reverse voltage protection, flexible wiring options, and compatibility with a wide range of load types, it provides a cost-effective and dependable solution for digital output control in industrial automation systems.
