The LW09 Module serves as DALI Master and generates DALI commands to control lighting systems. It features
two switch inputs for example, dim or control lightings, which are configurable via I2C interface. This means that
functions of the switches can be programmed via I2C.
Two potential free switches (or switch) can be connected at the DALI Master. This way, for example, a wireless
connection to DALI-Bridge system can be implemented to create switches, for dimming or change scene
functions for individual lights, groups or all lights.
There is no mains voltage needed! The DALI bus is used for power supply. The DALI Master can release
up to 15mA at 5V.
Important Notice: The DALI bus is not galvanically isolated, it is not allow to connect a different voltage source to
the DALI Master LW09.
