The ABB DG/S2.64.1.1 KNX DALI Gateway 2-fold is a compact Basic-class interface that connects ABB i-bus® KNX to two independent DALI / DALI-2 lines. Each output operates as a certified Single-Master controller (EN 62386) for up to 64 DALI participants, with integrated DALI bus power on both lines — all within one 4-module MDRC enclosure.

That means up to 128 DALI devices total (2 × 64) from a single DIN-rail position, with wide-range mains input and 4 W total power loss — ideal for larger floor plates where two DALI subnets are required without doubling panel space.

Key Features and DALI Capabilities

The DG/S2.64.1.1 delivers twice the DALI line capacity of the 1-fold Basic gateway while retaining the same modular width.

Dual DALI-2 Outputs

• Two independent DALI lines: 2 × 64 participants, 2 × 16 groups, 2 × 16 scenes — controlled individually or in broadcast per line.
• Integrated DALI PSU on both outputs: No external DALI supplies required for either line.
• DALI-2 Single-Master: Certified per EN 62386; controls DT6 luminaires and other standard DALI device types.
• Emergency DT1: Self-contained emergency converters (EN 62386-202) supported; function and duration tests via KNX.
• Built-in functions: Slave, staircase, force, block, and scene logic on each line.

Diagnostics, Commissioning, and Reliability

• Fault telegrams: Extensive fault and error reporting for each DALI line.
• Manual operation: Local test and override for faster commissioning.
• ABB i-bus® Tool: PC software for DALI addressing, grouping, and line diagnostics.
• ETS configuration: Dedicated .knxprod for DG/S 2.64.1.1 (Downloads tab).
• Software updateable: Firmware updates supported.

Applications and System Integration

• Large open-plan areas: Serve two DALI subnets (e.g. east/west wing or floor halves) from one gateway.
• Mixed emergency and general lighting: DT1 testing and switching on both lines through KNX.
• Panel space savings: Two DALI masters in the same 4M width as DG/S1.64.1.1.
• Project documentation: Data sheet, dual connection diagrams, dimensional drawing, CAD, and manuals under Downloads.

Choosing 1-fold vs 2-fold Basic Gateways

Use DG/S1.64.1.1 when a single DALI line is enough. Choose DG/S2.64.1.1 when the project needs two independent DALI subnets without adding a second gateway module. Premium DG/S x.64.5.1 models add tunable white and extended sequences for advanced lighting design.
