The ABB DG/S 2.64.5.1 DALI Gateway, Premium (order code DG/S2.64.5.1) provides two independent DALI-2 lines — up to 2 × 64 participants — with integrated DALI power supplies on a single 4 MW MDRC. Same Premium feature set as the 1-fold sibling: DT0/DT1/DT8, colour/HCL, groups, scenes, and load-control integration.

Ideal when one Premium gateway must serve two lighting buses. For a single line use DG/S1.64.5.1; for eight basic DT0 channels see DG/S8.1.

Key Features

• DALI-2 Premium, 2-fold: Two independent outputs × 64 devices each.
• DT0 / DT1 / DT8: Emergency (DT1) and colour (DT8) on both lines.
• 16 groups / 16 scenes per output: Full scene control per DALI bus.
• Colour & HCL: Dim2Warm, RGB(W), HSV(W), human-centric sequences.
• Standby / load control: Coordinate with energy modules for peak limiting.
• 4 MW MDRC: Dual-line gateway without doubling panel width vs Premium 1-fold.

• Single-line projects: Prefer the lighter DG/S1.64.5.1.

Installation Notes

Mount on a 35 mm DIN rail (4 MW). Connect KNX, mains auxiliary, and both DALI outputs. Commission with the Premium 2-fold ETS application from Downloads. Keep DALI lines electrically separate; do not parallel the two outputs.
