4-way button interface
KNX 4-way button interface
Intended use
¦ Inputs for querying conventional, potential-free contacts in KNX systems and sending telegrams to the KNX bus to report statuses, meter readings, operating consumers, etc.
¦ Outputs for controlling LEDs
¦ Installation in a device box with dimensions in accordance with DIN 49073 in combination with a suitable cover
¦ When installing behind switch and button inserts, use a device box with sufficient installation depth
Product features
¦ Independent channels that work as inputs or outputs depending on the ETS parameterization
¦ Common reference potential for all channels
¦ Locking of individual channels
¦ Supply via bus, no additional supply voltage required
¦ KNX Data Secure compatible from ETS 5.7.7 or from ETS 6.1.0
¦ Can be updated with ETS service app
Outputs
¦ Connection of LED e.g. LED lamp, 5 V DC, 2.2 mA
¦ Short-circuit-proof, overload-proof and protected against
reverse polarity ¦ Parallel switching of outputs possible for consumers with higher power requirements
Inputs
¦ Connection of potential-free contacts such as buttons, switches or reed contacts
¦ The query 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, color temperature, RGBW, temperature or brightness values
¦ Transmission of the current input status after bus voltage failure
¦ Connection of door or window contacts for evaluating the status open, closed, tilted and handle position
¦ Connection of leakage, condensation and temperature sensors
¦ Pulse counter with main and intermediate counter
¦ Combination of adjacent input channels when connecting buttons, door or window contacts
¦ Logic functions
