The Metro Dali one relay provides addressable control of non-Dali light sources and other devices such as fan-coils, blinds etc within a Dali environment.
The unit is typically used in applications where the majority of controlled lights are Dali and yet certain luminaires are not available with Dali ballasts but need to be switched, or where other devices such as water valves, VAV units or window blinds require to be controlled.
The Dali One Relay connects to the Dali buswire which links Dali luminaires, sensors and other devices to the Dali control module: the 16A mechanicallylatched relay operates in response to commands transmitted along the Dali bus.
The unit derives its power from the incoming 230V circuit. Integral LEDs indicate power & diagnostic functions while a selector switch configures the relay for control of normal lighting or discharge lighting (inhibiting frequent switching).
