I/O
Modules
Node
The DALI/DSI Master module has no power jumper contacts. The field
supply potential of the adjacent I/O modules in the node will not be passed to
the following modules. A supply module is therefore required to provide any
additional I/O modules.
Danger
It is not allowed to remove a live module.
2.1.1.7.3 DALI Bus Line
The DALI bus control line consists of one pair of conductors which can be run
together with the 230 V installation.
For example, a 5-conductor cable can be used combining both the voltage
supply and the DALI control line.
The minimum cross section of the conductors depends on the cable length.

1.5 mm²
Attention
The maximum voltage drop of the DALI line should not exceed 2 V.
Therefore, the maximum cable length between the more distant components is
limited to 300 m.
2.1.1.7.4 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.
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“).
