Switching/dimming actuator 3-way KNX, 1-10V. Switching/dimming actuator for dimming lighting circuits via remote dimmers and electronic ballasts with 1-10V interface. For each channel, the controlled devices can be switched off via a potential-free normally open contact when OFF. A lighting scene control for 8 scenes with preset brightness values is integrated. Dimming speed, brightness when switched on and behavior after a power or bus failure can be adjusted. The switching status of the outputs is sent to the bus via separate feedback objects. The device is also equipped with a manual control that is independent of the bus and cannot be overridden and LED switching status displays.
