Brightness controller

Stock no. 5WG1255-4AB1..

Stock no. 5WG1255-4AB1..

  • For measuring the brightness on an illuminated work area through measurement of the reflected light

  • Measuring range 0...2000 lux (with a reflectance of the illuminated area of approx. 30%)

  • Including two rigid optical fiber rods:

  • Parallel light-sensitive surface for mounting surface

  • Inclined (30°) light-sensitive surface for mounting surface

  • Integrated infrared receiver for calibration of the brightness measurement via the S 255 infrared remote calibration tool

  • Transmission of the brightness measured value, either in the event of change and/or cyclically

  • Discretionary set-point as a parameter or a communication object

  • Optional two-step dimmer control for lights that can only be switched or constant light level control for lights that can be switched and dimmed

  • Selectable starting value of the lighting at the start of constant light level control

  • Optionally with dimming of up to 4 further lighting groups to the dimming value of the constant light level control or a dimming value that differs from the dimming value of the constant light level controller by an offset value, which can be set per group

  • The constant light level control is automatically deactivated by manually dimming, or by dimming to a preset value

  • Configurable behavior in the event of a bus voltage recovery
