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

Installation Guidelines

Mounting: Snap directly onto a standard 35 mm DIN rail conforming to EN 60715. Ensure the locking latch engages securely.
Wiring: Insert a small screwdriver into the clamp spring release slot to open the connection point, insert the stripped conductor (9 to 10 mm stripping length), and release the spring clamp.
Pluggable Block: Ensure the power supply is completely switched off before engaging or disengaging the pluggable terminal wiring block.
Shielding: Connect analog signal shields to the nearest functional ground bar to prevent environmental electromagnetic interference from affecting signal integrity.

Key Features:

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.
