Description
Introduction
The theben DALI-Gateway S64 KNX (Item no. 4940301) acts as an intelligent interface connecting DALI lighting infrastructure directly to a standard KNX system. Designed for seamless interoperability in modern building automation, this 1-channel gateway enables central control and communication for up to 64 DALI members or lighting units. This device is part of our KNX system components range.
DALI-2 certified, the device operates on a broad mains supply voltage of 100 V AC/DC to 240 V AC/DC (50/60 Hz) while drawing less than 10 mA from the KNX bus connection. Featuring standard 4-width DIN rail mounting and screw terminals, it integrates reliably into electrical distribution boards for commercial and institutional installations.
