The KNX S4-B12 24 V actuator with integrated facade control has 4 outputs for direct current drives (12...24 V DC up/down), 4 pairs of buttons and control LEDs. The outputs are suitable for drives for blinds, awnings, roller shutters or windows. The connected drives can be operated directly on the KNX S4-B12 24 V and via manual buttons. The automatic function can be set 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). Twelve binary inputs can be used either for direct operation (e.g. manual button) or as bus buttons (or also for e.g. alarm messages). The desired behavior can be precisely defined by selecting the reaction times in standard, comfort or dead man mode.
