| Model function |
KNX Secure line coupler/repeater with Data Secure; the catalog identifies the 02 variant as available by request. |
| Power supply and current |
Main line and subline each use 21–30 VDC KNX TP. Current consumption is below 10 mA from the main TP line; each line segment needs its own KNX bus power supply. |
| Interfaces |
KNX protocol on both the main-line and subline interfaces; galvanic isolation between the two TP sides. |
| Routing and commissioning |
Use the TP Coupler application for line/area coupling and the TP Repeater application for unfiltered data transfer between galvanically isolated line segments. |
| Telegram filtering |
Filters traffic according to bus hierarchy and built-in group-address filter tables. Manual function permits temporary filter switch-off and special routing, repetition and confirmation settings for commissioning and troubleshooting. |
| Long telegrams |
Supports tracing of subline traffic. The 2025-04-18 series catalog specifies up to 240-byte APDU. |
| Repeater topology |
Up to four line segments can form one KNX TP line using three KSC repeaters. Provide an independent KNX power supply for each segment and follow the coupler hierarchy; do not directly bridge separate lines around their couplers. |
| Bus connections |
B3 is the main-line KNX TP terminal; B4 is the subline KNX TP terminal. Both use red + / black −. B1 is the Function button and B2 the Program button. |
| Main-line status |
Green: main line OK; red: manual function active. |
| Subline status |
Green: subline OK. |
| Traffic indicators |
The main-line and subline traffic LEDs flash green with telegram traffic and flash red for transmission errors. |
| Address-routing indicators |
For both group-address (GA) and physical-address (PA) routing: green means filter active; orange route all; red block all; OFF means the main-line and subline settings differ. |
| Programming indicator |
Red: programming mode. |
