Description

Engineered for precise analog automation control, the BECKHOFF KS4434 analog output terminal delivers four channels of high-resolution control signals. Operating within a standard range of -10 to +10 V, this bus terminal features single-ended circuitry designed to drive analog actuators, control valves, and speed-controlled motor drives with precision.

A defining feature of the KS series is its pluggable wiring level, enabling fast, tool-free module replacement without disrupting existing system wiring. Integrating seamlessly into the Beckhoff K-bus system, the module transmits electrically isolated signals back to the automation controller, maintaining process stability and protecting sensitive upstream components from electrical noise.

Features

Four single-ended analog output channels.
Standard bipolar voltage signal range of -10 to +10 V.
12-bit analog resolution for fine control loop adjustments.
Pluggable connection level for swift, minimized-downtime maintenance.
Short-circuit proof outputs with active load protection above 5 kOhm.
Robust electrical isolation rated up to 500 V between K-bus and signal circuits.
Direct DIN rail installation with reliable double-slot side-by-side locking.

Applications

Industrial machinery and process control systems.
Variable frequency drive speed setting regulation.
Proportional valve control in hydraulic and pneumatic systems.
HVAC ventilation, damper, and actuator positioning.
OEM manufacturing lines and assembly automation.

Installation Guidelines

Mounting: Mount the bus terminal horizontally or vertically on a standard 35 mm DIN rail. Secure the terminal using the integrated lock mechanism.
Wiring: Use a flat-blade screwdriver to open the spring clamp terminal. Insert the stripped wire (9 to 10 mm stripping length) and release the clamp.
Shielding & Grounding: Ensure the analog signal cables are properly shielded to prevent electromagnetic interference from surrounding power circuits. Connect the shield to the ground plane closest to the entry point.
Pluggable Level: When servicing, slide the pluggable terminal connector out of the housing to disconnect wiring safely without terminal-by-terminal rewiring.

#Analog Output Modules #Beckhoff Bus Terminals

What is the key advantage of the BECKHOFF KS series over the standard KL series?

The KS series, including the KS4434, features a pluggable wiring level. This allows the terminal housing to be pulled out and replaced without disconnecting the field wiring, reducing maintenance time.

What signal range does the BECKHOFF KS4434 analog output terminal use?

The KS4434 outputs a bipolar voltage signal ranging from -10 V to +10 V.

Does the KS4434 require manual address configuration?

No, the KS4434 does not require manual address or hardware configuration settings; it is automatically mapped into the system's process image.

Is the analog output protected against short circuits?

Yes, the analog outputs are short-circuit proof with an active load protection recommended above 5 kOhm.
