Concept
DALI Inputs/Outputs without Power Distribution
The DALI light modules have four DALI inputs/outputs, which are designed for control of DALI light control gear such as lights with electronic ballasts, LED drivers, and other control gear with DALI interface as well as connection of DALI input devices such as sensors and push-buttons.
The four DALI inputs/outputs are labeled Light 1 to Light 4.
The DALI inputs/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.
DALI inputs/outputs without power distribution
The four DALI inputs/outputs share one logical DALI channel.
The 2-pole DALI input/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 the DALI control gear and input devices on the DALI bus. Each DALI control gear device is assigned a unique short address, which is used when communicating with the individual device on the bus. The DALI control gear and input 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.
Up to 16 DALI input devices in total can be connected to the DALI light module. Each input device supports up to four sensors or buttons.
