According to the variant, two, four or eight independent channels that operate as inputs or as outputs depending on the ETS parameterisation.
Common reference potential for all channels.
Outputs: Connection of LED. Short-circuit-proof, protected against overload and polarity reversal. Parallel switching of outputs possible, for consumers with higher current requirements
Inputs: Pulse current to prevent contact contamination due to formation of an oxide layer on the connected contacts.
Channels can be activated and deactivated individually.
Adjacent activated channels can be combined.
Possible parameterisation depending on the selected channel function
Contact type can be set.
Switching: Command when pressed and/or released can be set (No reaction; Switch on; Switch off; Switch over).
Forced setting: Command when pressed and/or released can be set (No reaction; Forced active, Switch on; Forced active, Switch off; Forced inactive).
Dimming and colour temperature: The command when pressed, time between switching and dimming, dimming in different steps, telegram repetition if pressed for a long time and sending of a stop telegram at the end of pressing can be set.
Blind/shutter/awning/roof window: Command when pressed and command sequence can be set.
Value transmitter: Data point type, value range and value can be set. As an option, the value adjustment can be activated by pressing and holding the button.
Scene auxiliary unit: Scene number can be retrieved or switched by briefly pressing the button. If the button is pressed and held, the memory function is executed as an option.
Short and long button press: Up to two telegrams can be sent to the KNX by pressing a button. The transmission behaviour can be set and the time for short and long actuation can be adjusted. The mode of operation of the channels can be set separately.
Room temperature controller operating point: The mode of operation (operating mode switch-over, forced operating mode switch-over, presence function and setpoint temperature shift) can be set.
Behaviour after bus voltage recovery can be set.
Disable function can be set.
Cyclic transmission can be set.
Channel function “Door/window status”: When door or window contacts are used, the different window or door statuses can be evaluated (open, closed, tilted, locked, unlocked).
Evaluation of a leakage/condensation sensor.
Temperature measurement by connected sensor possible.
Temperature measurement can be supplemented by external value via bus. Measured values can be weighted and calibrated.
Pulse meter
Metering interval can be set.
Number of pulses required at the input per reported meter pulse can be parameterised on the KNX.
The number of meter pulses required for a meter status change can be parameterised.
Each channel contains a main meter and an intermediate meter.
Main and intermediate meters can be set separately as up or down meters.
Start and end values of the meters can be specified via parameters or communication objects.
Meter status can be queried via the KNX or transmitted automatically.
Response after the meter has timed out can be parameterised.
The pulse meter can be reset via the KNX (meter reset).
Logic functions
The device has 8 internal logic functions.
Invert input.
Logic gate with up to 4 inputs: AND, OR, exclusive OR, inverted AND, inverted OR, inverted exclusive OR, AND with return.
1-bit to 1-byte converter with input filter, blocking object and specification of output values.
Blocking element with filter and time functions and blocking object.
Comparator for values with 9 different input data formats and many comparison operations.
Limit value switch with hysteresis with upper and lower threshold values for 9 different input data formats. Including specification of the 1-bit output values.
The logic functions have their own KNX communication objects and can process telegrams from the button interface or other bus devices.
