ELSNER 70550 KNX S1R-B4 compact Multifunctional Actuator- 4 Binary Inputs

The Actuator KNX S1R-B4 compact with integrated façade control has got a multifunctional output which can connect to either a drive with Up/Down control (blinds, awnings, shutters, windows) or two switchable devices (On/Off for light and ventilation). Because the output is designed to be free of potential, other systems can also be controlled, e.g. via the manual switch input on a motor control unit.

Automation can be specified externally or internally. Internally, there are numerous options available for blocking, locking (e.g. master-slave) and priority definitions (e.g. manual-automatic). Scenes can be saved and called up via the bus (scene control with 16 scenes).

4 digital inputs are available for the connection of binary contacts. A zero position sensor or pushbutton, for example, can be connected here.
