Description
Introduction
The theben Line coupler Sec KNX (Item no. 9080048) is a high-performance system component designed to structure and expand KNX building automation topologies. Functioning as an area coupler, line coupler, or segment coupler, it enables logical isolation and data routing between distinct bus lines, optimizing overall network performance. This device is part of our KNX automation components range.
Engineered for standard DIN rail mounting, this device operates on a 24 V DC supply with a minimal KNX bus current consumption of ≤10 mA. When utilized as a segment coupler to extend a main line with additional subline segments, it offers full operational support specifically when configured using ETS 6 software.
