DALI light controller 4-way surface mounting - KNX light system interface DLR/A4.8.1.1

DALI light controller 4-way surface mounting - KNX light system interface DLR/A4.8.1.1 – ABB – 2CDG110172R0011 – 4016779882378: DALI light controller 4-fold AP DLR/A4.8.1.1 bus system KNX, other bus systems without, design interface lighting system/DALI, type of installation flush-mounted, with LED display, updateable, operating voltage 230V, protocol other, protection class (IP) IP20, surface-mounted Device for switching and dimming 8 independent lighting groups. A maximum of 64 DALI participants can be connected to a DALI control output. In conjunction with 4 connectable light sensors LF/U 2.1, the device can be used as a light controller for constant light control. In this function, the device can be a key component in energy-efficient building automation. In addition, a staircase light and a master/slave function are available in the device. Extensive fault messages, eg about electronic ballasts and lamp errors, are transmitted on the KNX. Thanks to its surface-mounted housing, the DALI light controller can be used as a central device in the false ceiling or in the underfloor area.
