The ABB DG/S1.64.1.1 KNX DALI Gateway is a compact Basic-class interface between ABB i-bus® KNX and digital DALI / DALI-2 lighting. As a certified Single-Master DALI controller (EN 62386), it controls up to 64 DALI participants on one integrated DALI line — with built-in DALI bus power — from a single 4-module MDRC DIN-rail position.

Wide-range mains input (85 … 264 V AC or 110 … 240 V DC) and low power loss (2 W) make it suitable for standard distribution boards in offices, retail, hospitality, and institutional projects.

Key Features and DALI Capabilities

The DG/S1.64.1.1 bridges KNX building automation with professional DALI lighting control without separate DALI power supplies or additional gateway hardware.

DALI-2 Control and Capacity

• Single DALI output: One DALI line for up to 64 DALI devices (DT6 luminaires, DT1 emergency converters, and other EN 62386 participants).
• Integrated DALI PSU: Bus power for the DALI line is included — no external DALI supply required.
• Flexible control paths: Switch and monitor via KNX using individual addresses (64), groups (16), scenes (16), or broadcast.
• Advanced DALI functions: Slave, staircase, force, block, and scene functions are integrated for practical day-to-day operation.
• Emergency lighting (DT1): Supports self-contained emergency converters per EN 62386-202; function and duration tests can be triggered via KNX.

Diagnostics, Commissioning, and Reliability

• Fault reporting: Extensive fault and error telegrams for maintenance and BMS integration.
• Manual operation: On-device test and override for commissioning.
• ABB i-bus® Tool: Separate PC software for DALI address assignment, group configuration, and diagnostics.
• ETS integration: Import the official .knxprod application (Downloads tab) for parameterisation alongside other KNX devices.
• Software updateable: Firmware updates supported over the product lifecycle.

Applications and System Integration

• Commercial lighting: Connect KNX presence sensors, schedules, and touch panels to DALI luminaires in open-plan offices, corridors, and car parks.
• Emergency compliance: Centralise DT1 emergency testing and reporting through KNX visualisation or BMS.
• KNX + DALI projects: One gateway per DALI line — ideal where a single DALI subnet serves up to 64 fittings.
• Documentation: Data sheet, connection diagram, dimensional drawing, CAD, and installation manual are available under Downloads.

Choosing DG/S Basic Gateways

ABB offers DG/S1.64.1.1 (1 DALI line) and DG/S2.64.1.1 (2 independent DALI lines) in the Basic range, plus Premium variants with tunable white and extended sequences. Select the 1-fold model when one DALI subnet is sufficient; choose the 2-fold model to serve two lines from the same 4M width.
