As result, each bus line KNX installation can operated
electrically independently the other lines.
Area/line coupler
-
- Use area line coupler, depending the specification of
the physical address and parameterisation.
-
- Telegram confirmation the main and subline possible
separately for group telegrams and physically addressed
telegrams with the settings "always" and "for forwarding only".
-
- Forwarding group telegrams can parameterised.
Scope supply
-
- KNX connection and junction terminal included the scope of
supply.
-
- "Forward unfiltered" and "block" functions can also selected
for physically addressed telegrams between main and subline in
both communication directions (programming and tamper
protection).set 1129 D538
Features
-
- The uninterruptible power supply 640 generates the
KNX system voltage.
-
- Telegram confirmation can parameterised.
