.cAnnexAnnexTechnical features of a <strong>DALI</strong> circuitMaximum no. of <strong>DALI</strong> units: 64Maximum no. of <strong>DALI</strong> groups: 16Maximum no. of <strong>DALI</strong> scenes:16<strong>DALI</strong> voltage: 9.5 V – 22.5 V, typically 16 V<strong>DALI</strong> system current: Max. 250 mA (depending on the installed <strong>DALI</strong> power supply)Data transfer rate: 1200 baudMaximum cable length: The maximum cable length depends on the maximum permitted voltage drop along the<strong>DALI</strong> cable; this is defined as 2 V max. This corresponds to a maximum cable length of 300 m for a linecross-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....<strong>DALI</strong> Manual | 08-2013 | en86 / 93
