Lighting control based on wired DALI controllers
Wired control systems based on DALI are a definite solution for places where there is no cellular or other wireless reception,
The wired controllers are installed at distances of up to 200-250 meters between the controller and the farthest lighting unit.
On each DALI line (two-wire cable) you can install up to 64 lighting fixtures (in separate addresses), the controllers come in two configurations (DALI one channel, DALI two channels).
