JUNG 2073U KNX vodilni vmesnik 3

The JUNG 2073U KNX Bus Coupler 3 is a high-quality flush-mounted device designed for integrating conventional push-buttons and switches into KNX building automation systems. It provides three binary inputs for potential-free contacts, enabling flexible control of lighting, blinds, and other electrical loads. The bus coupler is powered directly via the KNX bus and is configured using the ETS software, supporting a wide range of functions including switching, dimming, blind control, value transmission, scene control, and sequence control. Integrated logic functions (AND, OR, XOR, time functions) allow for advanced automation scenarios without additional components.

Advantages

Reliable and precise integration of conventional switches into KNX systems. Compact flush-mounted design saves space and fits standard device boxes. Versatile input functions and built-in logic reduce the need for extra modules. Compatible with JUNG switch ranges (A, CD, LS series) for a uniform appearance.

Suitable for

• Residential and commercial KNX installations
• Retrofitting existing push-buttons into smart building automation
• Controlling lighting, blinds, heating, and other loads via KNX
• Projects requiring flexible input configurations and logic functions
