ABB TB/U12.8.1-CG Busch-tacteo KNX Control Element 12-gang

Description

Introduction

The ABB TB/U12.8.1-CG Busch-tacteo KNX Control Element 12-gang (Order Code: 2CKA006300A1544) is a high-end capacitive glass touch panel designed for modern room automation in KNX twisted-pair systems. Engineered with a frameless glass aesthetic, this 12-gang panel integrates switching, dimming, blind control, value transmission, and customized scene management into a single flush-mounted interface. This device is part of our KNX panel products range.

Equipped with an integrated KNX bus coupler, the device connects directly to standard KNX TP lines operating between 21 and 30 V DC without requiring an external auxiliary power supply. Built-in proximity and room temperature sensors provide automated backlighting on approach and room climate feedback, delivering an intuitive operational solution for contemporary residential and commercial architectural projects.
