The Schneider Electric MTN6725-0004 is a Merten KNX DALI Gateway Basic with two independent DALI outputs. It connects the KNX bus to two DALI lines for centralised, energy-efficient lighting control in larger zones or split open-plan areas.

Each output operates as a single-master application controller (Category I per EN 62386) with an integrated DALI power supply for ECGs. The device controls DALI edition 1 and 2 gear in mixed operation on both lines. Mains supply is 100–240 V AC. Like the single-output variant, it does not support DALI-2 input sensors on the DALI bus — use KNX presence detectors instead. For one DALI line, see MTN6725-0003. ETS application 7312/4.0 covers both SKUs.

Key Features — Dual-Output DALI Gateway

DALI and KNX

• DALI outputs: 2 independent (up to 64 ECGs per line).
• Control role: Single-master application controller per output (Category I).
• Integrated DALI PSU: On-board supply for ECGs on each DALI bus.
• Standards: EN 62386 edition 1 and 2 (mixed ECG operation).
• ETS application: DALI Gateway family 7312/4.0 (shared with MTN6725-0003).

Applications and KNX Integration

• Dual-zone offices: Separate DALI lines for open plan and meeting rooms under one KNX gateway.
• Retail and hospitality: Independent dimming curves per zone; scenes from MTN6215 touch panels.
• Presence on KNX: Pair with MTN630819 Argus presence on the TP bus (not DALI-2 sensors).
• BMS visualisation: Integrate with LSS100200 SpaceLYnk for DALI-aware building logic.
• Single-line alternative: MTN6725-0003 when only one DALI output is required.

Choosing MTN6725-0004 vs MTN6725-0003

Choose MTN6725-0004 when two DALI lines must be controlled from one KNX device. Use MTN6725-0003 for single-line installations with the same single-master behaviour and ETS application family.
