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.

Key Features:

#Beckhoff KS Series #Bus Terminals

What is the primary difference between Beckhoff KS and KL series terminals?

The KS series terminals (such as the KS4004) feature a pluggable connection level that can be detached from the housing. This allows the terminal electronics to be replaced without disconnecting the pre-wired terminal blocks.

Does the KS4004 require an external power supply connection?

No, the KS4004 does not use external power contacts. It is powered internally via the standard Beckhoff K-bus, consuming typically 85 mA.

What is the output voltage and channel capability of the KS4004?

The KS4004 provides 4 analog output channels, each capable of outputting a 0 to 10 V signal with 12-bit resolution.

Is the analog output protected against short circuits?

Yes, the analog outputs on the KS4004 are short-circuit proof for loads greater than 5 kOhm.
