This Light Dependent Relay (Twilight Switch) is from the Finder 11 Series, and is used for the automatic control of lighting according to the ambient light level. The relay is for 35mm DIN Rail mounting, with an input voltage rating of 230V AC 50-60Hz and 16A output (+ auxiliary output for Power Module). The settings with LCD status indication, include Daily time switch function that is programmable to inhibit main output (for energy saving) and Auxiliary output which is directly driven by the photosensor. The relay has an Italian patent ‘Light feedback compensation' principle.
There is an internal battery for set-up/programming without supply and for time/program back-up in case of power failure (5 years), a sensitivity adjustment from 2 to 150 lux.
