The LCN-BT4H can be used either as a 4-way binary sensor or as a button converter for mains voltage (230VAC) for all LCN bus modules from version 140719 (July 2010). The 4 inputs of the LCN-BT4H evaluate signals of any phase position against N. The inputs are galvanically isolated from the I connection. When functioning as a button converter, the commands short, long & off are triggered in the A table, when functioning as a binary sensor, the commands long & off are triggered in the B table. The LCN-BT4H can be switched using DIP switches so that it works as a button converter or as a binary sensor. When functioning as a button converter, conventional buttons can be evaluated. As a binary sensor, for example, timers or other permanent contacts can be evaluated.
