The Universal KNX Actuator System is a fully modular actuator system where extension modules can be plugged-in to extend the number of output channels as needed. Up to 72 channels can be combined for switching, shutter or blind, heating, dimming, analog 0-10V or LED drivers with various size and power.
Extension modules can be plugged-in next to the master module to add extra channels using more than 10 different types of extension to fit exactly the project requirements.
Up to 8 extension modules can be added to the master actuator. Depending on the extension type, you can drive up to 72 outputs with the actuator system using a single KNX interface.
The system uses limited space with compact modules. The Master actuator is made for mounting on DIN rail and covers 4TE.
Each channel of the master module and the switching extensions can be configured as a switch or a shutter actuator, this gives a high level of flexibility and can be used in any application. Therefore, the universal actuator combines the advantages of the shutter actuators with the one of the switching actuators.
In shutter/blinds operation the relay contacts of the actuator can be used to control electrically driven blinds, shutters, awnings, venting louvers or similar curtains for 230 V AC mains voltage. Alternatively, the actuator can switch electrical loads, such as lighting systems in switching operation including staircase, flashing or PWM valve control functions.
The controls on the front panel of the master device (4 pushbuttons) permit switching the outputs ON and OFF manually in parallel with the KNX bus, even without bus voltage or in a non-programmed state. This feature permits fast checking of connected loads for proper functioning.
Scope
This manual covers the MSA-810 master actuator and the channel functions available through its extension modules. The master provides eight 10 A switching channels. The functions available on an extension depend on its type. Check the system limits before selecting modules.
