Status messages of DALI
operating devices
On/off, dimmer setting, length of operati-
on, 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, poten-
tial-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.
Acc. to DIN VDE 0100, Part 520, Section
528.11, main circuits and associated auxil-
iary circuits can be laid together, even if
the auxiliary circuits conduct a lower volt-
age than the main circuits.
Maximum system
current
Maximum current of the central interface
supply is around 250 mA.
Each connected device can consume a
maximum of 2 mA.
Power supply No dedicated power supply is needed.
Transmission
Transmission technology serial, asynchronous
Baud rate 1,200 bit/s
Device properties
