STEINEL Light Sensor Dual DALI-2 IPD light sensor, square surface-mounted, white

Name: STEINEL Light Sensor Dual DALI-2 IPD light sensor, square surface-mounted, white
Brand: STEINEL

The STEINEL Light Sensor Dual 057411 is a surface-mounted light sensor with a DALI-2 Input Device interface. Its square white plastic housing has a circular measuring face. It supplies light measurements to a higher-level control system; it is neither a motion detector nor a stand-alone switch for a mains-powered lamp.Directed and diffuse light measurementsLight Sensor Dual measures both directed and diffuse light. It combines information from the area below the sensor, such as a desk surface, with the surrounding room brightness. The connected management system therefore receives measurements covering both aspects, rather than relying only on a general ambient reading.The twilight setting spans 2–1000 lx, and the TEACH function allows a brightness threshold to be learned. Settings are made via the bus. This IPD version communicates measurements to a DALI-2 system; it should not be confused with the KNX version or treated as an autonomous constant-light controller.Powered by the DALI busThis version operates from the DALI bus at 12–22.5 V as an addressable slave device. An appropriate higher-level DALI application controller is needed to use its measurements in a lighting installation. Do not connect the sensor directly to a 230 V supply. Plan the connection and other system components using the manufacturer's wiring diagram.There is no integrated motion detector. If a project also needs occupancy information, this sensor's light readings do not replace that function. The distinction matters when specifying a system that must respond both to daylight and to the presence of people.Housing size and installation positionThe front measures 95 × 95 mm and the housing is 42 mm deep, finished in white RAL 9003. Wall and ceiling installation are supported at heights of 2–4 m. The manufacturer lists offices, classrooms, conference rooms and high-bay warehouses as applications. Indoor and outdoor use are specified, with an IP54 housing and an ambient temperature range of -20 to +50 °C.Pokaż więcej
