Concept
DALI Light Outputs without Power Distribution
The DALI light modules have four Light outputs, which are designed for control of lights with electronic ballasts, LED drivers, and other control gear with DALI interface.
The Light outputs support DALI lighting control. Power distribution (100 to 277 VAC) to the control gear is not supported but needs to be accomplished with an external power supply.
The four Light outputs share one logical DALI channel.
The 2-pole Light output connector has two terminals for DALI lighting control:
DA+
DA-
These two terminals are where the wires from the DALI bus are connected. The DALI bus is a 2-wire bus, which is used for bi-directional communication. For more information, see Wire Sizes and Lengths .
The DALI light module monitors and controls each control gear device on the DALI bus. Each control gear device is assigned a unique short address, which is used when communicating with the individual device on the bus. The control gear devices can be arranged into up to 16 groups. Each device can be a member of any combination of the 16 groups. For example, a group can be used to change all LED drivers in a room from Off to On.
Up to 32 DALI control gear devices can be connected to the DALI light module. For more information, see section “Specifications”.
