Datasheet

Features
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 lx)
- 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 2 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)
• 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)
