BECKHOFF KS3448 Bus Terminal

Description

Processing analog input signals in compact industrial control setups requires reliable, high-density I/O interfaces. The BECKHOFF KS3448 analog input terminal processes up to eight signals in the 0 to 20 mA range with 12-bit resolution. Designed with single-ended technology, this module features a highly compact design form and pluggable wiring levels, easing installation and maintenance in dense control cabinets. It operates directly via the K-bus backplane connection, transmitting digitized process signals to the higher-level automation controller without requiring manual address or hardware configuration.

Features

• Provides 8 single-ended analog inputs optimized for 0 to 20 mA current loops.
• Features pluggable wiring levels (KSxxxx series) allowing rapid module exchange without disturbing existing field wiring.
• Features a compact housing design with high packing density for maximum space utilization in control cabinets.
• Delivers 12-bit conversion resolution with a fast conversion time of approximately 4 ms.
• Equipped with 500 V electrical isolation between the K-bus and the process signal voltage.
• No address or software configuration parameters needed for standard integration.

Applications

• Industrial process control monitoring analog current loops.
• Factory automation environments using K-bus controller architectures.
• Machine manufacturing requiring high-density analog sensor interfaces.
• Water treatment, environmental monitoring, and building automation installations.

Technical Specifications

Installation Guidelines

• Always isolate all power supplies to the K-bus station and field devices before installing or removing the terminal.
• Mount the terminal securely onto a standard 35 mm DIN rail conforming to EN 60715. Ensure the locking mechanism engages completely.
• Maintain clear ventilation space around the terminal stack to prevent localized heat buildup, ensuring operation remains within -25 to +60 degC.
• To insert field wires, actuate the spring-clamp using a standard terminal screwdriver. Strip wire insulation to a length of 9 to 10 mm.
• Maintain proper system grounding and shield terminations to protect sensitive analog inputs from electromagnetic interference.
