SOU-2 | Twilight switch with digital time switch clock + photosensor SKS


  • Is used for control of lights on the basis of ambient light intensity and real-time (a combination of SOU-1 and time switch clock SHT-1 in one device).
  • The time clock can override the light sensor for applications when lights are not required.
  • Adjustable light intensity 10-50000 lx.
  • Function „random switching“ enables simulation of presence in a house when nobody is at home.
  • Switching: according to a program (AUTO) / permanently manual/random (CUBE).
  • External sensor IP44 is suitable for mounting on the wall / in panel (cover and sensors are part of delivery).
  • The sealable transparent cover of the front panel.
  • Backup of data and time by battery (reserve battery up to 3 years).
  • Easy replacement of backup battery with a plug-in module located on the front panel of device (no disassembly required).
  • 2-MODULE, DIN rail mounting.

SKS | Photosensor


  • The sensor is installable to panel (by the screw-able transparent cover) to opening with diameter 16 mm. A part of the sensor is a plastic holder for placing into the wall or to another place. Length of a line connector to the sensor cannot be more than 50 m. Doublecure cable can be used as wire diameter min. 2x 0.35 mm2 and max. 2x 2.5 mm2 .
  • The protection degree is IP44. To keep this protection: - photoresistor cover must be sealed by a rubber circle (part of the sensor) - cable must be of round cross-selection - the opening must be tight to the used cable
  • It is possible to use photoresistor, which changes resistance in accordance with ambient illumination, as a sensor. Tolerance sensor ± 33 %.
  • The light sensor can not be used alone.
