About This Product
The bus coupler has 8 inputs and 8 outputs. It can be switched to 16 outputs
(default factory setting: 16 outputs).
The bus coupler therefore occupies two or four bus addresses on the sensor actuator bus line
(AS-i network).

The control elements, the LED displays, and the bus coupler connections are shown in
