ETS product family: Input
Product type: Binary input

Intended use
Inputs for polling 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 parameterization
Common reference potential for all channels
Disabling individual channels
Supply via bus, no additional power supply necessary
KNX Data Secure compatible with ETS 5.7.7 or ETS 6.1.0 or higher
Can be updated with the ETS Service App
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
Connection of floating contacts, such as push-buttons, switches or reed contacts
Polling 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
