The KNX S1R-B4 compact actuator with integrated facade control has a multifunctional output to which either a drive with up/down control (blinds, awnings, roller shutters, windows) or two switchable devices (on/off for light and ventilation) can be connected. The potential-free design of the output means that other systems can also be controlled, e.g. via the manual button input of a motor control unit. The automatic function can be specified externally or internally. Internally, there are numerous options for locking (e.g. master-slave) and priority settings (e.g. manual-automatic). Scenes can be saved and called up via the bus (scene control with 16 scenes per drive). 4 digital inputs are available for connecting binary contacts. A zero position sensor or button, for example, can be connected here.
