Relays
For groups that switch rather than dim, and for loads too large to dim.
Relays are used where the lighting should switch rather than dim, and where the load is too large for a driver. Sports halls, outdoor lighting and non-dimmable luminaire groups are the typical cases.
With a relay in the Casambi network you get the same scenes and schedules as for dimmed groups, but at on/off level. That goes a long way when the goal is that nothing should be left burning unnecessarily.
Frequently asked questions
It is stated in the datasheet per model. Account for the inrush current of LED drivers; it is considerably higher than the rated power and is the most common reason a relay wears out early.
Yes. The groups are handled separately in the app, so a hall can have dimmed spectator lighting and relay-controlled pitch lighting in the same network.
