The LDALI-BM2 pushbutton coupler integrates traditional light pushbuttons and switches into a DALI channel. With CEA-709 / DALI or BACnet / DALI controllers, a compact control module with 4 programmable switching inputs is available. When the pushbutton is pressed, DALI commands are sent to a DALI group within the DALI channel or to another DALI channel available on the DALI controller to which the line is connected (via L-DALI controller).
Each input receives its own functions regardless of the switching behavior (short or long press of a button, pushbutton, pushbutton or switching mode). The following functions are available: On with last dimming value, Scene recall: 1-15, Dim to a specified value in %, Warmer / cooler color temperature, Active auto mode.
In switching mode, the function is executed depending on the lighting status (pushbutton switch).
The LDALI-BM2 module is connected directly to a DALI channel and also powered by that channel.
