Product Description

Description

Acquisition of analog sensor signals within automated industrial networks is performed efficiently using the BECKHOFF KS3142 analog input terminal. This high-precision Bus Terminal provides dual-channel connection capabilities for field sensors operating with standard 0 to 20 mA signal currents. Utilizing a robust differential input design and a 16-bit analog-to-digital converter, the module delivers highly accurate measurement data directly to the K-bus process image. The distinctive feature of the KS-series housing is its pluggable wiring level, which enables fast assembly and easy replacement of the terminal block without disconnecting the established field-side wire connections.

Features

  • Two-channel analog input module processing 0 to 20 mA field signals.
  • High-resolution 16-bit analog-to-digital conversion with increased measuring accuracy.
  • Configurable conversion time and integral 50 Hz filter to eliminate signal noise.
  • Pluggable connection level allows quick terminal swapping during maintenance operations.
  • Differential inputs with 500 V galvanic isolation between the K-bus and field signals.
  • Integrated surge voltage resistance up to 35 V DC for enhanced field protection.

Applications

  • Machine building and precision assembly equipment
  • Industrial process instrumentation loops
  • Water and wastewater treatment facility monitoring
  • Power generation and thermodynamic plant controls

FAQ
What is the key advantage of the KS3142 pluggable wiring design?
The pluggable terminal block on the KS3142 allows the core unit to be unplugged and replaced during maintenance without having to disconnect or tag the individual signal lines.
Can the conversion times and filters of the KS3142 be adjusted?
Yes, both the conversion time (default 140 ms) and the internal 50 Hz filter parameters can be configured through the bus coupler software settings.
Does the KS3142 have standard ATEX ratings for hazardous locations?
Yes, the module is certified under ATEX with the Ex marking: II 3 G Ex nA IIC T4 Gc, making it suitable for Zone 2 hazardous areas.
