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.

The DALI Gateway can be integrated into DALI emergency lighting systems. It allows interference-free operation of operating devices, general lighting systems and emergency lighting operating devices of the same DALI system. The device is able to integrate standard DALI operating devices for lighting control according to IEC 62386-101 (DALI System) and IEC 62386-102 (Control-Gear) into centrally-supplied emergency lighting systems as an emergency light. Alternatively or in addition, the DALI Gateway permits the control and function monitoring of individual battery operated emergency lighting operating devices, according to IEC 62386-202.
