BECKHOFF KS4004 KS Series Bus Terminal

Description

The KS4004 analog output terminal is designed to generate highly accurate analog signals within the range of 0 to 10 V. Engineered as part of the Beckhoff KS series, this 4-channel module features a pluggable wiring level that permits swift replacement during maintenance without disconnecting active field wiring. The terminal processes electrical signals with a resolution of 12 bits and transfers them, electrically isolated, to the process level. The power required to operate the module is drawn directly from the K-bus, eliminating the need for separate external power contacts.

This single-ended output terminal is optimized for compact control cabinets where high-density analog output signals and quick-disassembly capabilities are critical. With built-in short-circuit protection and an exceptionally low output error margin, the KS4004 guarantees stable command signal delivery to actuator drives, control valves, and other analog-driven field devices in complex process environments.

Features

• Four analog output channels with a 0 to 10 V signal range.
• Pluggable connection level for easy installation and tool-free module swap-outs.
• Internal power supply driven directly via the Beckhoff K-bus interface.
• Short-circuit proof outputs designed to handle loads greater than 5 kOhm.
• High-accuracy performance with a relative output error of less than +/-0.1 % of the full-scale value.
• No address or hardware configuration required prior to deployment.

Applications

• Industrial positioning systems and actuator control loops.
• Variable frequency drive (VFD) speed reference signaling.
• HVAC dampers and climate control system modulation.
• Standard machine building and process plant automation.

Installation Guidelines

• Mount the module vertically or horizontally on a standard 35 mm DIN rail conforming to EN 60715. Ensure the locking slide mechanism snaps securely into place.
• To prevent electromagnetic interference on sensitive 0-10 V analog lines, use shielded cables and connect the shield to a low-resistance ground terminal near the entry point of the control panel.
• Ensure that no field wiring is connected when plugging or unplugging the terminal wiring level to avoid transient electrical spikes.
