Description of the DALI output

On the DALI output, up to 64 DALI devices can be connected. The DALI Light Controller is a DALI master
with integrated DALI voltage supply.
Note
Other DALI masters may not be connected to the DALI output of the DALI Light Controller.
This can cause communication malfunctions in a single master system.
Note
Other DALI power supplies may not be connected to the output of the DLR/S. The connection of a
further DALI voltage supply can cause superimposition of voltages and lead to a malfunction of the
DLR/S.
Inadvertent connection of 230 V mains voltage to the DALI output will not destroy the DALI output stage.
The DALI output is protected by an internal self-restoring fuse.
A control line on the DALI output with the following maximum length can be used:
Cable length [mm]
Max. cable length [m] from the DLR/S
to DALI device
These values are rounded off and relate to the resistance values. EMC influences are not considered. For
this reason, the values should be considered as absolute maximum values.
It is possible to assemble the DALI control cable with conventional installation material for mains cables.
The two cores of the five-core NYM 5x1.5 mm
of the polarity. It is not mandatory to lay a separate control cable.
The isolation between DALI control cables and the power supply is assured by the simple insulation
properties according to EN 410. SELV properties are not featured.
