[email protected] www.nokeval.com Analog Outputs for Weather Transmitters by using serial converter 7470 Four outputs 4-20 mA The serial converter 7470 is designed to add analog outputs for measuring instruments which have only serial output. Typical application for 7470 is the multi-input weather transmitter WXT520 sending several weather parameters over serial bus. The 7470 is easy to congure to give analog outputs from all measuring sensors or calculated parameters of Vaisala weather transmitter WXT520. The serial converter 7470 can be placed up to 1 km from the transmitter with serial bus RS485. The 7470 has four analog output channels for serial input RS485 or RS232. More analog outputs are available by using several 7470 converters with serial bus RS485. The converter supports Modbus RTU, Nokeval SCL and ASCII protocols. The 7470 is easy to congure with MekuWin congurationsoftware on the computer. Typical outputs: Wind direction Wind speed Gust Temperature Power supply 24 VDC Vaisala Weather Transmitter WXT520 or WMT52 7470 WXT520 Weather multi-sensor Designed for demanding applications where stable and inexpensive wind measurements are required. The Vaisala Weather Transmitter WXT520 is a compact and lightweight multi-sensor instrument that measures the most essential weather parameters. It is a congurable product that can measure wind speed and direction, liquid precipitation, barometric pressure, temperature and relative humidity — all in one transmitter. WMT52 Ultrasonic Wind Sensor Designed for demanding applications where stable and inexpensive wind measurements are required. Humidity Barometric pressure Rain accumulation Rain intensity Power supply 24 VDC Several 7470 units can be connected in parallel on a serial bus RS485.
