The Beckhoff KL1498 Bus Terminal Digital Input is built to handle 8 digital inputs using 24 V DC nominal voltage with clear signal differentiation between โ€œ0โ€ and โ€œ1โ€ states. Its 0.2 ms input filter provides rapid response, while the typical input current of 3 mA ensures energy efficiency. The coupler consumes 5 mA from the K-bus and adds only minimal load on power contacts at 2 mA. With 500 V isolation and compliance to EN 61000 EMC standards, it guarantees stable operation in demanding environments.

Compact in design with 12 mm x 100 mm x 68 mm housing and weighing just 55 g, the KL1498 supports installation on 35 mm DIN rails and allows pluggable wiring for KSxxxx Bus Terminals. The polycarbonate housing includes diagnostic LEDs, making it easy for engineers to monitor system performance. The module withstands temperatures from 0ยฐC to +55ยฐC in operation, complies with EN 60068 vibration standards, and carries global approvals including CE, UL, ATEX, and IECEx, ensuring trust in industrial use.

Applications of the KL1498 Bus Terminal Digital Input include machine control panels, packaging systems, process monitoring, robotics, and building automation. Junior engineers find its plug-and-play configuration easy to set up without address settings, while experienced professionals appreciate its robust performance, fast response, and diagnostic clarity. Maintenance teams rely on its durability and IP20 protection rating, making it suitable for continuous use in automation cabinets. For industries requiring reliable Bus Terminals with high efficiency, the Beckhoff KL1498 is a trusted solution. Request a call back today to integrate this terminal into your automation project.
