US/U2.3 Universal Interface 2-fold: Flush-Mounted, Secure Push-Button & LED Integration
This Universal Interface is designed for modern requirements, supporting the KNX Data Secure standard to encrypt communication and enhance system integrity. Its small form factor makes it ideal for discreet installation directly behind switches or in flush-mounted boxes.
The US/U2.3 also provides capability for handling analog signals (0–10 V / 4–20 mA), further expanding its versatility beyond simple switching applications while maintaining a very low power loss of 0.25 W.
1. US/U2.3 Universal Interface 2-fold: Flexibility and Security
