KNX-BSA12H KNX blind actor module for controlling blinds and windows with 230 V AC drive
KNX-BSA12H is a KNX system shutter actuator for controlling the movement of curtains, blinds, awnings and windows with 230 V AC drive. The device has two physical outputs corresponding to two logical channels, each of which can control one selected type of curtain or window.
- KNX blind actuator for controlling blinds, shutters, awnings and windows.
- Two physical outputs and two logical channels, each for one type of curtain or window.
- Communication with KNX bus via integrated bus connector.
- Automatic detection of the curtain travel time and slat adjustment time.
- Manual control of curtain travel via buttons on the housing.
Application and functions of the KNX-BSA12H module
The KNX-BSA12H module is designed for building automation in the KNX system and is used to control devices equipped with a 230 V AC motor, such as horizontal (Venetian) blinds, roller blinds, awnings and motorized windows. With two logical channels, it is possible to control two curtains or windows independently, while selecting the type of curtain for each channel separately.
The device provides feedback on the status of the module and individual channels, making it possible to monitor the position of the curtains and the correctness of operation. The KNX-BSA12H supports weather alarms (rain, wind, frost), a position override function, and the ability to call scenes for each channel using 1- and 8-bit commands, allowing integration into advanced building automation scenarios.
Operation, configuration and installation
The KNX-BSA12H module communicates with the KNX bus via an integrated bus connector and is powered by 20...30 V DC from the KNX bus. Configuration of the device is carried out using ETS software, which allows detailed setting of operating parameters, curtain types, response to weather alarms and scene logic.
On the module's housing there are buttons for manual control of the curtains' movement and LEDs showing the status of each channel or curtain. The device is suitable for mounting on a 35 mm DIN rail, occupies 4 bays on the rail and has a 70 x 92 x 60 mm housing, making it easy to install in standard building automation switchboards.
Parameters expLoatation and electrical
The KNX-BSA12H is designed to operate in typical building automation environments, with an operating temperature range of 0°C to +45°C and a temperature range for storage and transport of -25°C to +70°C. The IP20 degree of protection means that the device is designed for indoor installation in properly protected switchgear.
The module has a KNX bus current consumption of less than 20 mA and a rated load supply voltage of 230 V AC. The permanent current carrying capacity of the contact is 6 A, and the maximum cross-section of the connection cable is 2.5 mm². In addition, the design of the device takes into account protections to detect a curtain error, such as lack of power supply, incorrect position, mechanical jamming or motor overheating.
