Finder 11 Twilight Switch For DIN-Rail - 11.41.8.230.0000

11.41 & 11.42 light dependent relay 12a/16a. 11.41. Patented "zero hysteresis" ensures reliable switching without wasting energy; patent pending for the "light feedback compensation" principle avoids the effect of the lamps repeatedly “hunting” between on and off, due to poor installation, again preventing a waste of energy. 4 position selector: light off (useful for vacations); light on (useful for installation); standard 1 to 80 lux threshold; high 30 to 1,000 lux threshold. For the first three working cycles the delay time (on and off) is reduced to zero in order to aid installation.
