Product Description

Description

Engineered for high-density space conservation in control cabinets, the BECKHOFF KL1889 is a High-Density (HD) Bus Terminal featuring sixteen digital inputs in a compact 12 mm housing width. Operating with negative switching (sink) logic, this module incorporates 1-wire connection technology, allowing direct connection of sensors and signals to the process image without excessive terminal blocks. Designed for seamless integration into K-bus networks, the KL1889 enables efficient signal acquisition in restricted spaces while simplifying wiring and minimizing hardware requirements.

Features

  • Provides 16 digital inputs within a compact 12 mm mechanical footprint.
  • Utilizes negative switching (sink) logic configuration.
  • Employs 1-wire connection technology with direct plug-in connection for solid conductors.
  • Tool-free termination for solid conductors; simple spring actuation by screwdriver for stranded wires and ferrules.
  • Integrated hardware input filter (typ. 3.0 ms) to suppress line bounce and noise.
  • Complete 500 V galvanic isolation between the internal K-bus and the field potential.
  • Address-free configuration for immediate plug-and-play installation within the Bus Coupler process image.

Applications

  • Space-constrained decentralized control systems and distribution cabinets.
  • Automated assembly systems, packaging machinery, and material handling lines.
  • Sensor signal concentration in industrial process automation.
  • General manufacturing and PLC I/O expansion environments.
