0-10V Converter

The 0-10V Converter has been designed to provide one or two 0-10V outputs (depending on the sensor) with high resolution, accuracy and reliability.

Ideal for the Davis Anemometer/Wind Vane. Provides 0-10V output for Wind Speed (0 to 200Km/h) and a 0-10V output for Wind direction (0º to 355º with 5º dead band).

Based on a microcontroller that manages one 16-bit digital-to-analog converter per channel, the device can be used with a huge variety of digital and analog sensors, allowing the user to set up the output range of each channel.

The device incorporates an independent sensor failure signal and 4 software-programmable alarms which can be connected to a relay board or to the inputs of a digital data logger. The serial port (TTL levels) is used to communicate with the device from a PC or a compatible system. The included weatherproof IP-65 enclosure allows an easy installation.
