This compact DALI input module allows seamless integration of push buttons, switches, and sensors into a DALI lighting control system, making it ideal for local scene control, switching, or sensor-based automation.

The Helvar 444 Mini Input Unit supports four digital inputs, which can be configured for different control functions within the Helvar Imagine system. Its small size allows for easy installation behind wall switches, inside junction boxes, or within luminaires — perfect for retrofit or new-build projects where space is limited.
