The Beckhoff KL2404 Bus Terminal Digital Output is engineered for precise and efficient signal switching in automation environments. Built with a robust polycarbonate housing and designed for installation on a 35 mm DIN rail, it offers durability while maintaining compact dimensions of 12 x 100 x 68 mm. The device supports 2-wire connection technology and operates at a 24 V DC nominal voltage, ensuring reliable compatibility with industrial control systems. With four independent digital outputs, each channel supports up to 0.5 A of output current and is short-circuit proof, making it suitable for controlling a wide range of loads including ohmic, inductive, and lamp circuits.
For operational safety, the KL2404 meets EMC immunity and emission standards (EN 61000-6-2/EN 61000-6-4) and has approvals such as CE, UL, CCC, ATEX, and IECEx, ensuring compliance with international industrial standards. The terminal features signal LEDs for easy monitoring of output states, and its spring-actuated connection system supports solid, flexible, and ferrule conductors, reducing wiring time during installation. With an IP20 protection rating, the unit is suitable for enclosed cabinet use in demanding environments, operating reliably in temperatures from -25°C to +60°C. Its K-bus consumption of just 9 mA ensures energy-efficient performance even in large I/O systems.
Applications of the KL2404 Bus Terminal Digital Output are widespread across Indian industries. It is commonly deployed in manufacturing plants for switching actuators, relays, and indicator lamps, while in process industries it manages load switching for pumps, valves, and solenoids. In panel building and machine automation, the module ensures precise control of field devices while reducing wiring complexity through its pluggable connection system. Engineering institutes also use the KL2404 in training setups, allowing students to gain hands-on experience with industrial digital outputs and PLC integration. Its proven performance, global certifications, and compact design make the Beckhoff KL2404 a trusted solution for OEMs, system integrators, and maintenance engineers seeking reliable and scalable I/O systems.
