Interra ITR104-1000 4 Channel DALI Binary Input / Push Button Interface

The Interra ITR104-1000 is a 4-channel DALI-2 binary input module that lets you connect conventional push buttons, switches or floating contacts to a DALI lighting installation. It converts simple on/off signals into DALI telegrams, so ordinary wall switches can control DALI ballasts and drivers without extra wiring.

Each of the 4 channels can be configured independently as a switch or a potential-free push button, and the module is powered directly from the DALI bus — no separate power supply is needed, keeping installation simple and compact.
