Description
Introduction
The Theben OSIRIA 230 SR KNX (Item no. 5009211) is a single-sided, round indoor clock engineered for integration into KNX building control systems. Designed with a clean aesthetic, it features a white metallic dial with black fine-line numerals, black bar hour and minute hands, and a distinctive red second hand to deliver clear visual time displays across commercial and institutional facilities. This device is part of our KNX automation components range.
Powered directly via the KNX bus line with an operating current consumption of ≤12 mA, this clock eliminates the need for separate external power supplies. A built-in 10-day power reserve ensures continuous, accurate timekeeping even during temporary bus power failures. It features a plastic housing with a Ø 300 mm dial dimension and operates reliably across an ambient temperature range from -5°C to 45°C.
