BECKHOFF KS3142 Bus Terminal

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.
