I
Relays for automatic control of lighting
according to ambient light level - with
separate light sensor
11.42 - 1 CO + 1 NO 12A output contacts
• Two independent outputs with individual lux
setting
• Selector with 4 positions:
- Standard range (threshold setting 1…80x)
- High range (threshold setting 20…1000lx)
- continuous light (helpful during installation and
initial testing and for maintenance purposes)
- light off (useful for vacations)
• For the first 6 working cycles (in total for
channels 1 & 2) the delay time (On and Off) is
reduced to zero in order to aid installation
• LED status indication
11.91 - 1 CO 16A output contact
(+ auxiliary output for Power Module)
• 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 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 light sensor
• 35mm rail (EN60715) mount
• Cadmium free contact material
• Cadmium free light sensor (IC photo diode)
11.42 11.91
• 2 independent outputs
• 2 individual lux settings
• 4 position selector
• Light dependent relay + time
switch
• Auxiliary output (light
dependent) with 19.91 power
module available
