Casambi Bluetooth-controlled 2-channel output controller. Drives existing 0-10V LED drivers, ballasts, or DALI gear directly from the Casambi mesh — Ch1: 0-10V (sinking, max 7 mA) or DALI; Ch2: 0-10V (sinking) or relay. Replaces a legacy 0-10V wall dimmer or DALI master with a Casambi-controllable output stage.
Key Benefits
The CBU-A2D wires to existing 0-10V LED drivers, ballasts, or DALI control gear in place of a legacy wall dimmer or DALI master. The downstream wiring stays as it is — the CBU-A2D becomes the new Casambi-controllable output stage.
Once connected, the driver joins the Casambi network and responds to app control, schedules, scenes, and any Casambi keypad or sensor on the same network — with no additional configuration.
Each channel drives either a 0-10V (sinking, max 7 mA) controller signal for analog LED drivers and ballasts, or DALI broadcast for digital gear. Mix per installation without changing the controller.
