Product Description

Description

The BECKHOFF KS4022 is a two-channel analog output bus terminal designed for the generation of industrial control signals within a modular Bus Terminal system. Utilizing single-ended technology, the terminal converts binary control values from the automation controller into standardized analog process signals. It integrates seamlessly into standard Beckhoff Bus Terminal configurations via the K-bus, communicating process data while providing galvanic isolation between the field level and the internal system bus.

Equipped with pluggable wiring levels, the KS4022 facilitates efficient installation and maintenance by allowing terminal blocks to be disconnected without disturbing the field wiring. This design supports industrial control architectures requiring reliable analog actuation, standard 35 mm DIN rail mounting, and dependable signal conditioning in decentralized automation environments.

Installation Guidelines

Ensure the entire control system is de-energized before performing any mechanical or electrical installation work.
Verify that the mounting rail is a standard 35 mm DIN rail conforming to EN 60715 and is securely grounded.
Click the BECKHOFF KS4022 onto the DIN rail next to an appropriate bus coupler, embedded PC, or preceding terminal, utilizing the double slot and key connection for side-by-side alignment.
Connect field wiring to the pluggable spring-actuated terminals using a suitable screwdriver, ensuring correct conductor stripping lengths of 9 to 10 mm.
Verify that the 24 V DC power supply to the power contacts and the K-bus connection are correctly established before applying system power.
Perform a functional check of the analog output signals and process data mapping via the controller engineering software during system commissioning.
