DALI push button coupler. The DALI push button coupler is a binary input device for insertion into a flush-mounted box. The device is powered via the connected DALI line. The device has 4 input channels for potential-free contacts. Installation switches or installation buttons can be connected. The required voltage is supplied by the DALI push button coupler (no additional voltage source required). Triggered by the connected buttons or switches, the DALI push button coupler sends telegrams via the DALI line to a central DALI controller.
