The ABB i-bus
open standards in the digital illumination control DALI (EN 62386) and the intelligent installation system
KNX (ISO/IEC 14543-3 and EN 50090) and, at the same time, allows energy-efficient, constant lighting
control.
Its surface-mounted design means that the DLR/A is suitable for installation in suspended ceilings or
underfloor to integrate remote DALI lighting areas into the KNX building automation. The DALI output of
the DLR/A can be used to connect up to 64 DALI devices. The 64 DALI devices can be individually
addressed and allocated as required in up to 8 lighting groups. Control using KNX is implemented
exclusively via these 8 lighting groups.
With 4 light sensors, up to 4 separate constant lighting controls are possible that additionally provide
enhanced comfort and automatic energy conservation.
Constant lighting control can:

reduce operating costs

save energy

guarantee an optimum working environment at constant brightness

provide enhanced lighting comfort in day-to-day operation
The occupancy is also automatically detected in addition to lighting control via a KNX presence detector,
an above average energy saving potential can also be achieved using KNX lighting technology alone. The
following graphic provides an overview of the energy that can be saved by the use of modern, automatic
intelligent installation systems.
