Push button interface 8x Comfort for KNX

Features

• Depending on the variant, two, four or eight independent channels, which work as inputs or as outputs depending on the ETS parameterization.
• Common reference potential for all channels.
• Outputs: Connection of LED. Short-circuit-proof, overload protected and reverse polarity. Parallel switching of outputs possible, for consumers with higher power requirements
• Inputs: Pulse current to prevent contact pollution from oxide layer formation on the connected contacts.
• Channels can be activated and deactivated individually.
• Activated channels can be combined.

Possible parameterization after the channel function is selected

• Contact type is adjustable.
• Switching: When pressing and/or letting go, it is adjustable (no reaction; turn on; turn off; switch it off).
• Compulsory position: Command when pressing and/or letting go is adjustable (no reaction; compulsion active, powering on; force active, switching off; compulsion inactive).
• Dimming and color temperature: When pressing, the time between switching and dimming, dimming in different stages, the telegram repetition during long operation and sending a stop telegram at end of the operation is adjustable.
• Jalousie / roller shutter / awning / Roof window: Pressing and the command order is adjustable.
• Specifying: Data point type, value range and value is adjustable. Optionally, the value adjustment can be activated at the long press of a button.
• Scene reference: Scene number can be called or switched at short press of a button. At a long press of a button, the memory function is optionally performed.
• Short and long press of a button: Up to two telegrams can be sent to the KNX bus by pressing a button. The transmission behavior can be adjusted and the time for short and long operation can be adjusted. The functionality of the channels is separately adjustable.
• Room temperature controller servant: The functionality (operating mode switching, forced operation mode switching, presence function and target temperature shifting) is adjustable.
• Behavior after bus voltage return is adjustable.
• Locking function is adjustable.
• Cyclic sending is adjustable.
• Channel function "door/window status": When using door or window contacts, the various window or door states can be evaluated (open, closed, tilted, locked, unlocked).
• Evaluation of a leakage/condensation sensor.
• Temperature measurement possible by connected sensors.
• Temperature measurement can be supplemented by external value via bus. Measured values can be weighted and matched.

Pulse counter

• Counting interval is adjustable.
• Number of pulses required at the input per reported count parameter on the KNX bus can be parameterised.
• Number of counting pulses required for a counter reading change can be parameterised.
• Each channel includes a main counter and an intermediate counter.
• The main counter and the intermediate counter can be set separately as a forward or reverse counter.
• Start and end values of the counters can be specified via parameters or communication objects.
• Meter reading can be queried via the KNX or automatically sent out.
• Behavior after the counter is parameterizable.
• Pulse counter can be reset via the KNX bus (counter reset).

Logic functions

• The device has eight internal logic functions.
• Entry invert.
• Logic gates with up to four entrances: AND, OR, Exclusive OR, inverted AND, inverted OR, inverted exclusive OR, AND with return.
• 1-bit to 1 byte converter with input filter, black object, and default of output values.
• Locking link with filter and time functions and suspension object.
• Comparer for values with nine different input data formats and many comparison operations.
• Limit switch with hysteresis with upper and lower threshold for nine different input data formats, incl. Precaution of 1-bit output values.
• The logic functions have their own KNX communication objects and can process telegrams of the button interface or other bus devices.
