PS8A

Evaluation Unit for weather data

The system PS8A records meteorological data and forwards it to the evaluation unit. Here, it is analysed against the default settings. The user can program the eight output relays integrated with the evaluation unit individually. The output signals are used for control of higher level modules and to control the motors for the ventilation units, shading units or other equipment. Digital inputs from bus systems or PLC can also be switched.


  • PS8A PS8A

Complete system, comprising evaluation unit, weather station and indoor sensor

Evaluation unit:

  • 8 relay outputs
  • Integrated keypad and display

Weather station P03/3:

  • Brightness measurement with three separate sensors for east, south and west. Twilight detection with special filters
  • Wind measurement: The wind strength is measured electronically and thus noiselessly and reliably, even during hail, snow and sub-zero temperatures. Even turbulent air and anabatic winds in the vicinity of the weather station are recorded
  • Temperature measurement
  • Heated precipitation sensor (1.2 watts): No error measurement with dew or mist, fast drying after the rain ends
  • Integrated GPS receiver
  • Combination mounting for wall or pole assembly; hinge arm mounting available as an option

T-KTY82 indoor temperature sensor:

  • Universal temperature sensor
