DALI Gateway Colour for KNX

Easily integrate more functions.

The DALI Gateway Colour for KNX forms the interface between a KNX installation and a digital DALI lighting system. The 1-gang variant of the gateway enables switching and dimming of DALI operating devices in a DALI system, the 2-gang variant in two separate DALI systems.

Irrespective of the configuration, up to 32 independent DALI groups are available for group assignment. If necessary, these can be supplemented by 64 individually addressed DALI device channels per DALI system for alternative control. Optional central control of all connected DALI components is possible (broadcast). This eliminates the need to start up DALI, which means that lighting systems with low functional requirements can be put into operation quickly and easily. Different lighting concepts can be implemented with the DALI Gateway Colour for KNX (for more information see below).

  • Available as a 1-gang variant, which can control up to 64 DALI operating devices, and as a 2-gang variant, which can control up to 128 devices
  • DALI Device Type 8 for TW, RGB, RGBW and HSV lights
  • Six different addressing types enable group-oriented, individually addressed or combined control of DALI lights
  • Colour functions are available in all groups, individual devices and scenes
  • Automated colour cycle at the touch of a button
  • Dim-to-warm function
  • Dynamic, time-dependent colour transition in Colour Transition Mode
  • Dynamic, time-dependent colour temperature transition via Human Centric Lighting (HCL)
  • Certified as a DALI-2 control device in accordance with IEC 62386 Ed. 2
  • Integrated DALI power supply

Versatile lighting concepts.

Tunable White
(DALI Device Type 8 – TW)

The DALI Gateway Colour for KNX supports the control of DALI operating devices of the “Tunable White” device type. With the Tunable White function, the colour temperature of the light can be flexibly adjusted from warm white to cold white.

  • The colour temperature can be controlled via relative or absolute dimming and also via scenes
  • Cold white light can be used in offices, for example, in order to improve concentration and warm white light in living spaces for relaxing comfort

Human Centric Lighting (HCL)

With Human Centric Lighting, a daytime colour temperature curve can be created for the implementation of biologically effective lighting. The colour temperature is controlled independently of the brightness control for each group and individual device using separate communication objects. As an alternative, it can be used per channel for colour control. The lighting scenario can be started at the simple touch of a button and can be dynamically and automatically adjusted over the course of the day.

  • Targeted improvement of health and well-being
  • Up to four HCL matrices that can be freely configured in terms of brightness and colour temperature can be activated and switched according to the time and day of the week
  • Numerous areas of application (offices, hotels, schools, hospitals, living spaces etc.)

Colour control
(DALI Device Type 8 – TW)

When using DALI operating devices of the “Colour Control” device type, the gateway enables colour temperature adjustment of DALI lights in order to alter the mood or lighting conditions in the space. The gateway enables flexible colour control in the “RGB”, “RGBW”, “HSV” or “HSVW” colour spaces.

  • In the RGB colour spaces, the colour can be controlled by relative or absolute dimming either via combined or separate communication objects according to the KNX specifications
  • In the “HSV” colour space, separate objects are available for absolute control of the light colour by hue (H), saturation (S) and brightness value (V)
  • The colour cycle (cyclical adjustment by hue) is used for automatic overall colour control of DALI lights and creates ongoing colour transitions that can be started and stopped at any time
  • The automatic brightness cycle adjusts the brightness in the entire brightness range in cycles, thereby creating individual brightness scenarios
  • Can be combined with time control functions
  • Colour control can be integrated into scenes

Colour Transition Mode

In RGB or RGBW lighting systems, Colour Transition Mode (CTM) enables flexible and creative control of colour via colour changes and helps to create atmospheric and visual effects.

  • Gentle, gradual changing of the light colour
  • Adjusting the speed of the colour transition
  • Particularly suitable for commercial and decorative lighting systems (in restaurants, hotels, discotheques or for stage lighting)
  • Four CTM matrices that can be freely configured can be activated and switched according to the day and time of the week and enable a variety of colour transitions
  • Each matrix allows individual colour preferences to be set, with or without brightness adjustment
  • Automatic adjustment of colour and brightness cycle
