The DALI Gateway forms the interface between a KNX installation and a digital DALI (Digital Addressable Lighting Interface) lighting system. The DALI Gateway allows the switching and dimming of a maximum of 64 lights with a DALI operating device (e.g. electronic ballast).Up to 6 different addressing types of the DALI Gateway allow group-orientated and individually- address control of DALI lights via KNX telegrams.This allows the integration of room-specific light control, for example, of open-plan offices, multipurpose spaces, production facilities, training and presentation rooms or showcases into the higher-level KNX building management. Depending on the configuration, up to 32 independent DALI groups are available for group addressing. For alternative control, these can be supplemented with 64 individually-addressable DALI device channels, as necessary. Optionally, master control of all connected DALI components is possible (broadcast). This means that there is no need to commission DALI, meaning that lighting systems with few functions can be started up quickly and easily (simplified configuration without DALI commissioning). The DALI Gateway is supplied completely via the mains voltage connection and makes the DALI system voltage (typ. DC 16 V) available. The device is designed for mounting on DIN rails.
Colour temperature control (DALI Device Type 8)
The DALI Gateway supports the control of DALI operating devices of the device type “Colour Control” (DALI Device Type 8) in the specific version “Tunable White (TW)”. This makes it possible to control the colour temperature of a lamp by means of suitable DALI operating devices and luminaires. The Gateway allows the colour temperature control via relative or absolute dimming as well as via scenes and effects. The colour temperature control is largely independent of the brightness control and luminaire used.
