Secure KNX Line Coupler

Code: EK-ID1-SEC-TP

New
Secure KNX Line Coupler

Description

The EK-ID1-SEC-TP secure KNX line coupler connects two KNX segments (for example, a KNX main line with a sub-line or a KNX line with a KNX area) while ensuring galvanic isolation between the lines.

The device features an extended filter table for groups 0–31 and supports KNX Data Security and KNX Long Frames. It is compatible with ETS® software version 5 and later. With the product database for ETS 6, the device also offers security proxy and segment coupler functionality.

The buttons on the front panel allow you to disable telegram filters for testing purposes. The LEDs indicate operational status and communication errors on the bus. The device features an integrated KNX bus communication module and is designed for mounting on a 35 mm profile rail. Power is supplied via the KNX bus (main line). As a secure interface, the device prevents unauthorized access to the system.

Connections and Installation

  • KNX TP main line connector (red/black)
  • KNX TP sub-line connector (red/black)
  • Mounting on 35 mm profile rail according to EN 60715 (1 modular unit = 18 mm)
  • Power is supplied directly from the KNX bus main line (no external auxiliary power required)
