Vantage Pro2 Modbus RTU Interface DIN Rail
Interfaces a Davis Vantage Pro2 Weather Station to a Modbus RTU network by converting between Davis's WeatherLink serial protocol and Modbus RTU.
THIS PRODUCT HAS REACHED END OF LIFE. OUR UPGRADED VERSION IS NOW AVAILABLE KTA-382. WHICH CAN DO BOTH MODBUS RTU AND MODBUS TCP/IP.
Our Modbus to Davis Vantage Pro2 Weather Station Gateway allows you to easily connect your PLC (Programmable Logic Controller), RTU (remote telemetry unit) or SCADA System to one of the following Davis weather stations:
- 6152 Cabled Vantage Pro 2
- 6162 Cabled Vantage Pro 2 Plus
- 6316 Cabled Weather Envoy (with Cabled ISS, ISS Plus, ISS Solar Fan Aspirated or ISS Plus Solar Fan Aspirated)
- 6152 Wireless Vantage Pro 2
- 6162 Wireless Vantage Pro 2 Plus
- 6153 Wireless Vantage Pro 2 Fan Aspirated
- 6163 Wireless Vantage Pro 2 Plus Fan Aspirated
- 6316 Wireless Weather Envoy (with Wireless ISS, ISS Plus, ISS Solar Fan Aspirated or ISS Plus Solar Fan Aspirated)
The gateway plugs into the weather station's console using the Davis WeatherLink cable (Weather Link for Vantage Pro Serial) and appears on the Modbus network as a Modbus RTU slave. This allows your programmable controller to monitor and carry out actions based on wind speed, wind direction, temperature etc.
