The Gira Universal Pushbutton Interface, 4-gang (1119 00), provides four inputs for integrating compatible external pushbuttons or contacts into a KNX building automation installation. Once configured in ETS, the interface can translate supported input actions into KNX telegrams for the project’s control functions. It is useful where conventional wall switches or other suitable contact devices need to be incorporated into a KNX system. The precise functions and electrical limits depend on the official product application and the connected devices. Before specifying it, review the wiring diagram, input characteristics, cable requirements and any installation limitations in Gira’s current documentation. Commission the interface with the correct ETS database and test each input in the finished system.
