The Siemens KNX Line Coupler secure N 140S11 enhances building automation with a versatile three-level coupler function (Area, Line, Segment Coupler) and secure commissioning, making it essential for resilient buildings. Beyond KNX Data Secure, it provides Secure Proxy, ensuring high-performance communication between secure and KNX classic segments. Its patented Intelligent Programming Protection is a standout feature providing active defense against cyber threats: it restricts external access to internal devices and their configurations while automatically granting access to external devices.
