Table 43: DALI bus power usage for different device types
LOYTEC DALI bus power supplies supply 116 mA or 232 mA depending on the model.
Two 116 mA bus power supplies can be connected to the DALI channel in parallel resulting
in a combined DALI bus power supply of 232 mA. The DALI bus power supply must not
exceed 250 mA.
8.4.3 Multi-Master Operation
The L-DALI is capable of multi-master operation. That is, it can be installed in parallel to
one or more other DALI master controllers on the same DALI network. However, all other
DALI master controllers must be multi-master capable in order to render a working DALI
system. Other DALI masters may be DALI multi-sensors with built in constant light or
occupancy controller functionality, DALI switches, buttons, and touch panels, as well as
other DALI controllers.
8.4.4 DALI Device Types
The L-DALI distinguishes between the following DALI device types:
DALI Ballasts
DALI ballasts are specified in IEC 60929 and the newer IEC 62386. The L-DALI supports
IEC 62386 parts 101 and 102 and the DALI device types specified in parts 201 to 209
(Edition 1 of all parts). See [9] for DALI ballasts tested with the L-DALI.
In addition the L-DALI support some vendor specific features (e.g. reading serial number,
determining nominal power) for OSRAM and Tridonic ballasts.
DALI Sensors
Currently the DALI standard does not specify DALI sensors. Thus, any “DALI sensors”
available use proprietary extensions of the DALI protocol. Nevertheless, the L-DALI
supports the following DALI multi-sensors

:
 LOYTEC LDALI-MS1 (see Section 8.4.4.1)
 Tridonic MSensor 02 5DPI 41 (see Section 8.4.4.3)
 Schneider Electric LA-11
