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 connec-
ted 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).
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.
KNX (in the past, European Installation Bus)
KNX is the installation bus for cost-effective and flexible solutions in intelli-
gent building technology for commercial and industrial buildings.
The KNX standard is a company-neutral standard which has been fixed
in the norm EN 50090. KNX devices are checked, registered and certified
by the Konnex Association in compliance with the standard.
