KNX/DALI DBE-64 extension

The DBE-64 is a full-featured DALI bus master extension module for the Elausys Universal KNX Actuator System. Designed to seamlessly bridge KNX automation with professional DALI lighting installations, this extension enables control of up to 64 individual DALI devices or organization into 16 DALI groups through a single KNX interface. The integrated web commissioning interface simplifies DALI addressing and testing without requiring specialized DALI commissioning tools.

The DBE-64 provides complete DALI bus master functionality with configurable channel capacity. In ETS, select between DALI Actuator 32-fold, 48-fold, or 64-fold configurations to match project requirements and optimize KNX communication object usage. Each KNX channel can be independently assigned to control a single DALI gear (addresses 0-63) or a DALI group (0-15), enabling flexible zone-based lighting control with custom labels for easy fixture identification.

The extension generates the standard 18VDC DALI bus voltage with internal current limiting protection at 230mA. An external 24VDC power supply capable of delivering up to 300mA must be connected to power the DALI bus output. All 64 DALI gears can be monitored in real-time for ON/OFF lamp status, and the system provides automatic gear failure detection with error status display for proactive maintenance.
