P04/3-RS485

RS485 Weather Stations

The P04/3-RS485 Weather Station measures temperature, wind speed, brightness and it recognizes precipitation.
The weather station sends the currently recorded weather data once every second. This data flow can be received and analyzed by an end device such as SPS, PC or MC.
The P04/3-RS485 has four connections. Data output is at terminals A and B. Terminals 1 and 2 are for the power supply (24 V DC). The connections are not resistant to pole reversal. Connecting them incorrectly will destroy the interface components.

Models:

N° 30152 P04/3-RS485-GPS, GPS receiver, output of UTC, position (degree of longitude, latitude) and solar position.
N° 30153 P04/3-RS485-CET, GPS receiver, output of Central European Time (CET), automatic summer/winter time switch-over.
N° 30154 P04/3-RS485 basic, without time reception.

  • Brightness measurement with 3 separate sensors for east, south and west. Recognition of twilight/dawn
  • Wind measurement: The wind strength measurement takes place 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: No false reports as a result of fog or dew. Dries quickly after precipitation has stopped
