KL2124 - Beckhoff Bus Terminal Digital Output

The Beckhoff KL2124 Bus Terminal Digital Output is a robust module designed for handling low-voltage output signals with precision and reliability. It supports 2-/3-wire connection technology and delivers four digital outputs operating at a 5 V DC nominal voltage. Each output channel is capable of supplying up to ±20 mA current, short-circuit proof, with a signal current of 8 mA, making it suitable for driving ohmic, inductive, and lamp loads. Integrated protection mechanisms and a typical input filter of 3 ms provide enhanced signal stability, while a K-bus current consumption of 14 mA and 16 mA power contacts ensure efficient operation across large I/O systems. The module maps directly into the process image with a 4-output bit width, simplifying PLC integration and system control.

The KL2124 is built in a durable polycarbonate housing measuring 12 x 100 x 68 mm and weighing approximately 70 g, making it suitable for compact control cabinet designs. It mounts securely on a 35 mm DIN rail and supports modular side-by-side installation via Beckhoff’s double slot and key connection. Each channel is equipped with signal LEDs for instant status monitoring, assisting engineers during commissioning and maintenance. Flexible spring-actuated wiring supports solid, flexible, and ferrule conductors, with cross-sections ranging from 0.08 to 2.5 mm². The module meets global compliance requirements with CE, UL, CCC, ATEX, and IECEx certifications, along with conformity to vibration and EMC standards, ensuring safe and reliable performance in industrial environments.

In practical applications, the KL2124 Bus Terminal Digital Output is used in automation systems requiring low-voltage signal outputs, including testing stations, machine tool control, and laboratory equipment. Its compact design and safe short-circuit-proof outputs make it particularly attractive for panel builders and OEMs who require efficiency and reliability in confined spaces. Maintenance engineers benefit from the clear diagnostic LEDs and simplified wiring that reduce downtime during troubleshooting. Additionally, engineering institutes and training labs utilize this terminal to demonstrate digital output handling, current limitations, and PLC interfacing for students. With proven durability, safety certifications, and practical usability, the Beckhoff KL2124 is a trusted choice for industries across India and worldwide looking for efficient Bus Terminal Digital Output solutions.
