Single DALI Network Router


The DDC905 single subnet router uses an ethernet connection (10/100Mbps) to connect to and control a local DALI network. Basic functionality is available 'out of the box' without any programming. The system software allows for advanced configuration and functional programming of the router.

The system provides energy saving features via presence detection and constant light functionality. Further automation can be achieved through scheduled events. Integration with other building systems can be achieved using OPC, Ethernet I/O or Tridian Graphical Interface Unit (available on request).

A PC can be connected to the system for diagnostics and logging purposes if required, but all data is stored within the system itself so there is no need for PC control in daily operation. The elimination of a central controller ensures no single point of failure can cause a total system shutdown.
