The Lunatone DALI-2 MC4L POTI is a DIN-rail push button coupler with a practical twist: alongside its 4 galvanically isolated mains-voltage inputs, it carries 4 front-panel potentiometers so the light level for each input can be adjusted on site — no laptop, no software, just a screwdriver. LEDs on the front indicate which inputs are active.Key features 4 × 230V switching inputs, galvanically isolated from the DALI bus 4 potentiometers for direct on-site light-level adjustment per input Status LEDs for active inputs Per-input configuration of target address, button behaviour and DALI commands via DALI Cockpit Macros: colour temperature, dynamic scenes, sequences, custom command lists; DT8 TC and RGB(W) supported Application controller active from the factory; switchable to instance mode for BMS integration (WAGO, Beckhoff) Bus powered (3.6mA), DALI-2 certified, multimaster capable Technical specifications Supply DALI bus, 3.6mA Inputs 4 × switching inputs for mains voltage, cable max. 10m (50m interference-free) Mounting DIN rail Dimensions 98 × 18 × 68 mm Connection max. 2.5 mm² Ambient temperature -20°C to +60°C · IP20 A favourite for maintenance-friendly installations — corridors, warehouses, back-of-house areas — where the facility team should be able to trim light levels without touching the commissioning software.
