Type 11.91 - Light Dependent Relay
- Brand: Finder
- Product Code: Type 11.91
Description: Type 11.91 Light Dependent Relay “twilight switch” for the automatic control of lighting according to the ambient light level – using a separate photosensor.
Auxiliary output, for use with 19.91 Power Module, provides an output directly related to the light level (i.e. without intervention of any time delays).
Features include:
“Daily” time switch function – programmable to inhibit main output (for energy saving)
Auxiliary output – directly driven by the photosensor
Italian patent “Light feedback compensation” principle
Sensitivity adjustment from 1 to 150 lux
LCD display for status indication, set-up and programming
Internal battery for set-up/programming without supply and for time/program back-up in case of power failure (5 years)
Low stand-by power consumption
SELV separation between contact and supply circuit
Double insulation between supply and photosensor
35 mm rail (EN 60715) mount
Cadmium-free contact material
Cadmium-free photosensor (IC photo diode)
