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
