Bus devices
Possible addresses max. 64
Possible groups max. 16
Number of bus devices
per line
max. 64 ballasts and 64 sensors
Number of possible
scenes per ballast
Up to 16 light values (scenes) per ballast
can be stored, regardless of any group
assignments that may be programmed.
Topology Parallel, star-shaped wiring, excluding
possible groups.
Ring-shaped wiring is not permitted.
Terminating resistors are not needed.
Status messages of DALI
operating devices
On/off, dimmer setting, length of
operation, lamp error
Control input Galvanically isolated from the line voltage
(potential-free); all bus devices operate
on different phase conductors.
Power supply
System voltage DC V DALI bus voltage: approx. DC 16 V,
potential-free, short-circuit-proof, where
0 V can range from -4.5 V to +4.5 V, and
16 V is in the range of 9.5 V to 22.5 V.
Maximum system
current
Maximum current of the central interface
supply is around 250 mA.
Each connected device can consume a
maximum of 2 mA in the case of ballasts,
and approx. 5 mA in the case of sensors.
Power supply No dedicated power supply is needed.
