1...10 V technology
Analogue interface for controlling electrical equipment. The brightness is
controlled in lighting technology via a polarised voltage at the control input.
This voltage is made available by the ballast.
Individual addressing and direct addressing of the individual devices is not
possible. It is only possible to switch off the devices by disconnecting the
mains voltage via a separate switch contact (e.g. relay).
The standard for ballasts is DIN EN 60929.
Arbeitsgemeinschaft DALI - AG DALI (Activity Group DALI)
The AG DALI is an amalgamation of manufacturers of controllers, ballasts
and DALI devices which is established under the umbrella of the ZVEI. The
activity group has set itself the task of developing the DALI standard and
carrying out shared marketing activities. The DALI manual for example was
issued by the AG DALI. This manual and further information can be found on
the home page of the AG DALI under www.dali-ag.org.
Broadcast
Broadcast or broadcast mode is a command which controls all the
connected DALI devices together. The DALI devices do not need to be
addressed in this operating mode.
DALI (Digital Addressable Lighting Interface)
Digital, manufacturer-neutral standard in lighting technology for bi-directional
communication between controllers and electronic equipment with a DALI
interface.
The norm is standardised in DIN IEC 60929 (appendix E4). Due to the large
range of functions and application possibilities of DALI, the DALI sections
are currently being extracted from the standard and written into a separate
standard designated as DIN IEC 62386.
64 devices can be addressed. 16 scenes and 16 groups are possible.
The digital DALI standard has a typical high level of 16 V DC (max. 20.5 to
11.5 V DC) and a low level of 0 V (max. 4.5 to –4.5 V DC). The usable data
transmission rate is 1200 bit/s.
The maximum cable length is 300 m. The control cable is not polarity-
dependent and must have basic insulation (no SELV). Two cables in a 5-
core NYM mains cable can be used as a DALI control cable.
DALI ballasts have a dimming range of 0.1 to 100%.
DSI (Digital Serial Interface)
Older manufacturer-specific digital standard in lighting technology for
communication between controllers and electronic equipment with a
corresponding DSI interface.
The standard was developed by the company TRIDONIC ATCO and is the
precursor of the DALI standard without indirect status feedback.
