BECKHOFF KS4434 Bus Terminal

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.
