Description
The HDL Buspro 4 Zone Dry Contact Module (HDL-MSD04T.40) accepts four dry contact inputs, for example from conventional switches, and links them to the HDL Buspro system. The inputs support both switching and dimming control. Channel status is shown via LEDs, and the module includes a built-in temperature sensor. The compact 45 x 45 x 16 mm module is installed in a back box, making it suitable for adding HDL control to existing switch positions.
