The blind actuators KNX SBA-4C-230 V receive KNX telegrams and control several blind motors with limit switches independently of one another.
Each channel is controlled with two monostable relays and can also be manually activated with the buttons at the actuator.
Each channel can be individually programmed through the ETS3/4. Status reports, blocking functions, central switch functions and extensive calibration and positioning functions are available for selection.
In the event of bus voltage failure or resumption, the switch positions of the relay can be individually programmed for each channel.
The device is planned for permanent installation on a DIN-rail (top-hat) in high voltage current distributors.
