Description

Industrial processing systems utilize the BECKHOFF KS3444 analog input bus terminal to interface standard 0 to 20 mA signals directly from the field level to the higher-level automation controller. This four-channel module features single-ended inputs and provides a highly space-efficient design with a pluggable wiring level, enabling fast, tool-free installation and maintenance. By operating directly through the standard K-bus, the unit transmits digitized process values back to the coupler or controller with a 12-bit resolution. Integrated electrical isolation of 500 V between the K-bus and the signal channels guarantees high noise immunity and signal integrity in demanding electrical environments.

Features

Four single-ended analog inputs handling standard 0 to 20 mA current loops.
Pluggable connection level (KS-series design) allowing pre-wiring and rapid terminal replacement.
Compact 12 mm housing width to optimize control cabinet and DIN rail space.
K-bus powered with a typical current consumption of 85 mA.
Reliable performance across a broad operating temperature range of 0 to +55 degC.
Sturdy design complying with EN 60068-2-6 and EN 60068-2-27 for vibration and shock resistance.

Applications

Chemical and petrochemical processing plants.
Water and wastewater treatment facilities.
Machinery manufacturing and factory automation.
HVAC and building automation controls.

Installation Guidelines

Mount the terminal on a standard 35 mm DIN rail conforming to EN 60715. Ensure the locking mechanism is securely engaged.
To wire the pluggable KS terminal, use a flat-bladed screwdriver to actuate the integrated tension clamp mechanism.
Ensure the system power supply is deactivated before plugging or unplugging the terminal wiring block to prevent damage to the K-bus connections.
Observe regional grounding and shielding guidelines for analog signal cables to minimize electromagnetic interference.

Key Features:

What is the primary difference between the Beckhoff KL3444 and the KS3444?

The KS3444 features a pluggable wiring level, allowing the terminal block connector to be detached from the main housing without disconnecting individual field wires. The KL3444 has a fixed wiring level.

Does the KS3444 require an external power supply for K-bus communication?

No, the KS3444 is powered directly via the K-bus backplane from the bus coupler or controller, drawing a typical current of 85 mA.

Is the Beckhoff KS3444 suitable for hazardous locations?

Yes, the KS3444 is ATEX certified with Ex marking II 3 G Ex nA IIC T4 Gc, making it suitable for Zone 2 hazardous areas when installed in an appropriate enclosure.
