56 Connect Devices
Maximum cable length 300 m!
The maximum voltage drop of the DALI line should not exceed 2 V. Therefore,
the maximum cable length between the more distant components is depending
on the conductor cross-section limited to 300 m.

DALI Bus Topology

A DALI Master can control a line with a maximum of 64 slaves consumming 2 mA
each. 16 separate groups and 16 separate scenes can be allocated to each
slave.
Additionally, up to 64 addresses for DALI sensors can be used. The actual
possible number of sensors is determined by the following factors:
• Number of addresses per multi-sensor
• Power consumption of the sensor
• Bus performance
For use with the DALI Multi-Master Module (753-647) are recommended max.
16 multi-sensors per module.
The topology of the DALI bus is not defined. Line, tree, star or mixed structures
are possible. However, ring structures should be avoided.
The same installation regulations apply for both lighting equipments and power
supply cables.
This also applies to the installation of special rooms ("harmonized installation
regulations").
