Advantages of the LOGO! solution
You can connect the lamps directly to LOGO! provided
the switching capacity of the individual outputs is not
exceeded. In the case of greater capacities, you should
use a power contactor.
Connect the brightness-sensitive switch directly to one
of LOGO!’s inputs.
You don’t need a time switch since this function is inte-
grated in LOGO!.
The fact that fewer switching devices are required
means that you can install a smaller sub-distribution unit
and thus save space.
Fewer devices are required
The lighting system can be easily modified.
Additional switching times can be set as required (stag-
gered switch-off pulses at the end of the day).
The brightness-sensitive switch function can easily be
applied to all lamps or an altered group of lamps.
