Maximum Dali Cable Lengths

A DALI line can be run up to 300m using 1.5mm squared twin active cable. The DALI specification allows for maximum 2V drop in the communication signal.

DALI lines do not require termination of the line and supports all wiring typologies except rings and closed loops (trees, branches and chains are all acceptable). 

The Dali Alliance has the following document for maximum cable lengths:

Additionally, the IEC 62386-101:2014 document provides the following information for the maximum cable length between any two bus units or bus power supplies.
