The KTA-2881 is a combination of the modified KTA-282 Modbus TCP Gateway and an optical rain sensor RG-11. It allows you to easily connect your PLC, RTU or SCADA System to the Davis Weather Stations and an extra RG-11 rain sensor.

The RG-11 Rain Sensor includes a DIP switch that allows it to be set up for the mode of operation that best matches the application.

RG-11 Modes of Operation:

  • Tipping Bucket Emulation-- Replace your tipping bucket with a low-maintenance alternative.
  • "It's Raining"-- Close a skylight at the first sign of rain, and open it when it stops raining.
  • Condensation / Frost Sensing
  • Wiper control
  • Irrigation Control-- No more watering during a downpour!
  • Drop Detection

Connect the RG-11 to the dry-contact input of the gateway, the relay output status of the RG-11 can then be accessed via Modbus TCP/IP or RTU.

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 TCP/IP or RTU slave. This allows your programmable controller to monitor and carry out actions based on wind speed, wind direction, temperature, etc.
