Some PWM RGB controllers have always been stand-alone ones that do not need to get the control devices. However for smart lighting, your control unit is better to supply increased functionality. The system will send sign to your controllers and several kinds of control signal are available plus RF/WiFi cordless, DMX, DALI then 0/1-10V. Each one of these signals are going to be decoded with controllers and also transformed into PWM signal. All controllers will be developed in accordance alongside corresponding get a grip on protocol to RF, DMX, DALI and 0/1-10V in order to receive the signal.
