Hager TYFS130 KNX Secure Line/Area Coupler

Connect and isolate KNX lines with data-secure telegram filtering and galvanic isolation in a compact 2-module DIN rail device.

Overview

The Hager TYFS130 is a KNX line/area coupler that links a main line or area with a sub-line or area, forwarding telegrams between them while filtering based on group and physical addresses. It supports KNX Secure (Data Secure) for encrypted communication, ensuring that only authorized devices exchange data. The coupler is powered directly from the KNX bus (21-30 V DC) and consumes a maximum of 10 mA, making it energy efficient for building automation systems.

What stands out

• KNX Secure (Data Secure) support for encrypted telegram transmission.
• Galvanic isolation between connected lines for electrical safety and noise immunity.
• Telegram filtering by group and physical addresses, with a buffer for approximately 150 telegrams.
• Compact DIN rail mounting (2 TE / 36 mm width) for efficient panel space usage.
• Two LEDs indicate bus activity and error status for quick diagnostics.
