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.

Installation Guidelines

Ensure the system power supply is completely disconnected before mounting or removing the terminal.
Mount the module onto a standard 35 mm DIN rail (EN 60715) with vertical or horizontal mounting orientation as required.
Ensure the side locking mechanism of the bus terminal engages correctly with adjacent terminals to secure reliable K-bus and power contact transmission.
Utilize appropriate shielding and grounding procedures for sensor lines to prevent electromagnetic interference from distorting input signals.
