Technical features of a DALI circuit
...
Maximum no. of DALI units: 64
Maximum no. of DALI groups: 16
Maximum no. of DALI scenes:16
DALI voltage: 9.5 V – 22.5 V, typically 16 V
DALI system current: Max. 250 mA (depending on the installed DALI power supply)
Data transfer rate: 1200 baud
Maximum cable length: The maximum cable length depends on the maximum permitted voltage drop along the
DALI cable; this is defined as 2 V max. This corresponds to a maximum cable length of 300 m for a line
cross-section of 1.5 mm².
½ CAUTION!
When calculating the maximum cable length the contact resistance must also be taken into account.
A voltage drop of 2V must not be exceeded.
