The KDA-64 series is used to connect a digital DALI lighting system to the KNX installation, incorporating room-based lighting control into the higher level KNX building management system.
The device transforms switch and dim commands from the connected KNX system into DALI telegrams, and status information from the DALI bus into KNX telegrams.
The KDA-64 series is a Category 1 device, in accordance with EN 62386-103. This means the device must only be used in DALI segments with connected ECGs, and not with other DALI control devices within the segments.
The power supply comes directly from the KDA-64, therefore an additional DALI power supply is not required or permitted.
The device comes in a 4 unit wide DIN Rail casing so it can be directly integrated into the mains distribution box. Connection to the KNX bus is via a bus connector, and the DALI Bus is connected via screw connectors on the device.
ECGs can be switched, dimmed and set to a defined value in 16 groups per gateway. In addition to group control, KDA-64 offers the possibility to individually control up to 64 ECGs.
