KNX Push-button interface, 8-gang
Description
Intended use
- Inputs for querying conventional, floating contacts in KNX systems, and transmitting telegrams to the KNX bus for reporting statuses, meter readings, operating electrical loads, etc.
- Outputs for controlling LEDs
- Installation in flush box with dimensions according to DIN 49073 in combination with a suitable cover
- When mounting behind switching and push-button inserts, use an appliance box with sufficient installation depth
Product characteristics
- Independent channels that operate as inputs or as outputs depending on the ETS parameterisation
- Common reference potential for all channels
- Disabling individual channels
- Supply via bus, no additional power supply necessary
Outputs
- Connection of LED e.g. LED lamp, 5 V DC, 2.2 mA
- Short-circuit proof, overload protected and protected against polarity reversal
- Parallel switching of outputs possible, for electrical loads with higher current requirements
Inputs
- Connection of floating contacts, such as push-buttons, switches or reed contacts
- Querying with a pulse current avoids contact contamination (formation of an oxide layer) on the connected contacts
- Operating functions: switching, dimming, blind, scene or room temperature control
- Value transmitter for dimming, colour temperature, RGBW, temperature or brightness values
- Transmitting the current input status after bus voltage failure
- Connection of door or window contacts for evaluation of the open, closed, tilted and handle position statuses
- Connection of leakage, condensation and temperature sensors
- Pulse counter with main and intermediate meters
- Combination of adjacent input channels when connecting push-button, door or window contact
- Logic functions
