Interface DALI 4M
DFDALI module allows to manage up to 32 DALI ballasts (or similar devices) through the Domino bus.
DFDALI module can be successfully employed in domestic and professional lighting applications, where systems communicating by the DALI protocol are used.
DFDALI module offers the following main features:
• all timing functions are accomplished by the module and it may be controlled by any real or virtual input of the system, by supervisor or by video terminal
• possibility of control from one or more pushbuttons connected to Domino bus
• Up/Down and Single commands may be defined for the manual regulation of lighting level
• automatic brightness regulation (also without DFCP)
• programmable ramp, in the range 0 to 60 seconds
• setting of minimum and maximum output levels
• dynamic lights scenes can be easily implemented through DFCP
• the current brightness level may be stored and then recalled; up to 16 presets are available to create “real time” lighting scenes; the preset will be stored in the non-volatile memory of the ballasts
• if a Domino or DALI bus failure occurs, the output level will be automatically set to a user-defined level
• diagnostics of short circuit on the DALI line and lamp failure
The 32 devices for each line can be controlled as follows:
- Broadcast: each command sent on the DALI line will be executed by all the connected devices, therefore all the related devices will behave in the same way.
- Individually: the commands will be individually sent to each device, therefore each single device will behave independently (needs addressing of DALI devices).
- Groups: the command will be sent to groups, therefore each group of devices will behave independently (needs addressing of DALI devices).
DFDALI module can operate in systems with or without DFCP controller. In all cases, the module can perform Up, Down and Single Command functions by real or virtual points; moreover, saving and recalling of sceneries can be accomplished by the module.
