KNX Secure 32A Switch / Shutter Actuator


ITS525-0204 KNX Switch / Shutter Actuator is a versatile and high-performance device designed for smart building automation systems. It enables reliable control of lighting, shutters/blinds, and heating applications through the KNX bus, ensuring safe, efficient, and flexible operation in residential and hotel projects.


Each output of the actuator can be configured independently for switching functions, while two consecutive outputs can be combined to control shutter or blind applications. Thanks to the integrated manual control buttons, connected loads can be operated directly from the device in case of KNX bus communication failure, ensuring uninterrupted control.


Powered directly via the KNX bus, the ITS525-0204 does not require an external power supply. All device parameters and functions are configured using ETS software. Advanced features such as timing functions, logic gates, scenes, feedback telegrams, and last-state memory provide maximum flexibility and reliability for modern automation projects.
