Replacement for N° 70138 KNX S4-B12 24V
The Actuator KNX S4-B12 24V with integrated facade control has 4 outputs for direct current drives (12...24V DC, Up/Down), 4 button pairs and control LEDs. The outputs are compatible with shutter, awning, blind or window drives. Connected drives can be operated directly at KNX S4-B12 24V and via a hand switch.
The automation can be specified externally or internally. Internally, there are numerous options available for blocking, locking (e.g. master-slave) and priority definition (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. hand switches) or as bus switches (or also for e.g. alarm notifications). The desired behaviour can be defined precisely through selection of the response times in Standard, Comfort or Deadman mode.
