Relays for automatic control of lighting
according to ambient light level - with
separate light sensor
11.31 - 1 NO 16A output contact
• Sensitivity adjustment from 1 to 100lux
• One module, 17.5mm wide
• Low energy consumption
• 24VDC/AC supply version available
11.41 - 1 CO 16A output contact
• European patent “zero hysteresis” for energy
saving
• Italian patent “Light feedback compensation”
principle
• Selector with 4 positions:
- Standard range (threshold setting 1…80lx)
- High range (threshold setting 30…1000lx)
- continuous light (helpful during installation
and initial testing and for maintenance
purposes)
- light off (useful for vacations)
• For the first 3 working cycles the delay time
(On and Off) is reduced to zero in order to aid
installation
• LED status indication
• 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)
11.31 11.41
• 1 pole
• 17.5mm wide
• 1 pole
• “zero hysteresis”
• 4 position selector
