The Lunatone DALI-2 MC4L is a DALI-2 push button coupler with 4 galvanically isolated inputs for 230V mains voltage — the device that turns any conventional wall switch or retractive push button into a DALI-2 control point. It hides behind the switch in a standard flush-mounted installation box and is powered directly from the DALI bus.Key features 4 × 230V switching inputs, galvanically isolated from the DALI bus Each input individually configurable: target address, button behaviour, DALI commands Standard functions (dim, switch, scenes) plus macros: colour temperature, dynamic scenes, sequences, user-defined command lists DT8 tunable white and RGB(W) control supported in application-controller mode Bus powered — only 3.3mA consumption, no external supply DALI-2 certified, multimaster capable, configured via DALI Cockpit Choose your factory configuration App Controller (86458507-4L-2-app): application controller active — controls the DALI line directly Integration (86458507-4L-2-int): instance mode for BMS integration (WAGO, Beckhoff and similar) NFC (86458507-4L-NFC): application controller plus NFC configuration via smartphone and the Lunatone NFC app Technical specifications Supply DALI bus, 3.3mA Inputs 4 × 230V switching inputs, max. cable to button 10m (50m interference-free) Mounting behind switch, flush-type back box Dimensions 59 × 33 × 15 mm Ambient temperature -20°C to +60°C · IP20 Successor to the DALI MC4L, now with full DALI-2 certification. Ideal for retrofit projects that keep the existing 230V switch wiring.
