1-channel Universal Dimming Actuator, in small housing.

Phase control dimming technology (leading- or trailing-edge), being valid for different types of load RLC+LED:

230V~ Dimmable LED lamps.
12V~ Dimmable LED lamps with electronic transformer.
Incandescence and 230V Halogens.
12V Halogens with electronic transformer.

It has 4 Analog/Digital inputs, which can be configured independently, through the ETS:

Digital inputs (binary): allows the connection of a pushbutton, switch or conventional binary sensor, free-voltage contact.
Analog inputs: allows the connection of a temperature probe (ST KNT 001 or ST KNT 002).
Motion Detector: by connecting the sensor DM KNT 004.

Each of the four inputs has the following functions: Switch, Switch/Dimmer, Multiple Dimmer, Sequential Switch, Blind Control, Scene Control, Fixed/Forced Function, Counter and Temperature Sensor.
In addition, it allows to enable and configure up to 4 independent Thermostats.
It admits the connection of an Auxiliary Pushbutton (D) for the control of the Dimming.
Actuator or of another different actuator. Its functionality must be parameterized through the ETS.
Protected against overloads and short circuits. It incorporates heating protection of resettable operation.
Mounting into junction box.
Programming and commissioning by ETS5 or later version.
