New Sec KNX line coupler with Data Secure
With the Sec KNX line coupler, Theben is expanding its KNX portfolio with a powerful coupler for areas, lines, and segments. The device reliably connects two KNX TP lines (e.g., main and sub-line) while also providing galvanic isolation.
A special highlight: the line coupler supports secure communication in accordance with the KNX Data Secure standard, thus offering maximum security in the KNX system.
