1. LK/S 4.2 KNX Line Coupler: Advanced Communication and Security

This coupler is designed for maximum efficiency and robust data handling in segmented KNX networks.

Topology and Efficiency:

• Functions: Can be configured as a Line Coupler (connecting a line to a main line), an Area Coupler (connecting a main line to an area line), or a Repeater (signal booster).
• Data Security: Fully supports KNX Data Secure communication, filtering and processing secure telegrams to maintain network integrity.
• Filtering: Features built-in filtering mechanisms, including filtering by main group addresses (e.g., groups 14…31 with ETS4), to minimize unnecessary bus traffic.
• Isolation: Provides crucial electrical isolation between the coupled segments.

Compliance and Standards:

• Long Frame Support: Supports long frames for higher data payload and compatibility with newer KNX devices.
• Low Power: Extremely low power loss of just 0.3 W.
