KNX Line Coupler Secure

The Honeywell KNX Line Coupler Secure is a compact KNX TP/TP device designed to seamlessly connect two KNX bus segments, such as a KNX line with a KNX area or backbone. It provides reliable galvanic isolation between connected KNX segments, ensuring improved system stability and protection while supporting extended group address filtering for optimized bus traffic and enhanced overall network performance. Fully compatible with ETS® engineering software and supporting KNX long frames, the device offers flexibility for modern KNX installations. Integrated front-panel push buttons allow temporary bypass of telegram filtering during commissioning and troubleshooting, while onboard LED indicators provide clear visual feedback on operating status and communication errors, simplifying system monitoring and maintenance.

• The Honeywell KNX Line Coupler Secure is designed to simplify installation and enhance the performance of KNX building automation networks. Its compact DIN-rail mounting design allows for easy integration into electrical panels, while direct power supply from the KNX main line eliminates the need for additional power sources. Multi-color LED indicators provide clear visibility of operational status and diagnostic information, and local manual override functions enable quick testing and commissioning of group and individual address routing.
• The device offers flexible KNX topology support by connecting two KNX bus segments, whether as a line coupler, area coupler, backbone coupler, or repeater. Support for KNX long frames ensures compatibility with advanced KNX installations and facilitates seamless communication across extensive KNX networks. This flexibility makes the coupler suitable for both small-scale and large-scale building automation projects.
• To ensure reliable and secure communication, the Line Coupler Secure incorporates KNX Security Proxy functionality, enabling communication between secured and unsecured KNX lines. Galvanic isolation between KNX bus segments improves network stability and protection, while the extended filter table supports KNX main groups 0 to 31. Automatic filter table generation via ETS optimizes bus traffic, reduces unnecessary telegram transmission, and enhances overall system efficiency.
• Fully compatible with ETS® 5 and later versions, the device can be configured and managed using standard KNX engineering tools. Its professional-grade functionality simplifies system commissioning while supporting scalable and future-ready KNX installations, making it an ideal solution for secure, efficient, and high-performance KNX network integration.

• The Honeywell KNX Line Coupler Secure is designed to meet key international standards for safety, electromagnetic compatibility, environmental compliance, and secure KNX communication. The device is KNX Secure Certified, ensuring protected communication within KNX installations. It complies with EN 60529 IP20 requirements for indoor protection and meets the EMC Directive 2014/30/EU to ensure reliable electromagnetic performance. The coupler is also RoHS compliant under Directive 2011/65/EU and Amendment 2015/863, restricting the use of hazardous substances in electronic equipment.
• In addition, the device carries CE compliance and conforms to relevant standards including EN 63044-3:2018, EN 63044-5-1:2019, EN 63044-5-2:2019, EN 63044-5-3:2019, EN 61000-6-2:2019, EN 61000-6-3:2021, and EN 63000:2018, demonstrating compliance with functional, safety, EMC, and technical documentation requirements. The product also adheres to the WEEE Directive 2012/19/EC, supporting environmentally responsible disposal and recycling practices.
