TA 2.1 KNX
Dual Pushbutton Interface for KNX Systems
KNX Data Secure
Item No.: 4969272
Product Description
The TA 2.1 KNX is an advanced dual pushbutton interface designed for integration into KNX installations. This module functions as a pushbutton interface for binary input and binary output, supporting KNX Data Secure for secure system communication. Thanks to the four-wire cable connection, installation is simple and flexible.
The TA 2.1 KNX can be directly combined with conventional pushbuttons or switches and fits perfectly in standard flush-mounted boxes. Users can freely assign all functions, including switch/pushbutton, dimming, blind control, value transmitter, sequences, and LED control. The flexible LED control allows both commercially available LEDs and low current LEDs to be operated with an output current of 3 mA.
The inputs can be configured as outputs if required. Pair identification by color codes makes installation particularly clear and safe. This KNX component meets high demands for reliability and flexibility in modern building automation.
Applications
- Control of lighting, dimmers and blinds via KNX system
