| 135-100 Wind Translator Board & 135-102 Digital-to-Analog Board |
The 135-100 Series Translator Boards are a complete line of analog signal conditioning interfaces for almost any sensor input and desired output. Circuit boards utilize the latest technology in low-power solid-state components. They can be used individually or in combinations to create customized systems. NEMA-4X, mast mount, 19" rack mount, and desktop enclosures are available.
The Model 135-100 Wind Translator Board provides signal conditioning for wind speed and direction with voltage or current output. The circuit provides a regulated voltage to the wind direction potentiometer and converts wind speed pulse, ac or switch closure sensor outputs to a dc output. 0-100 mph and 0-360° typically = 0-5 Vdc outputs.
The Model 135-102 Precipitation D-to-A Conversion Board converts digital pulses to voltage or current output. Use with tipping bucket rain gauges or other pulse output devices like contact anemometers or flow sensors. The circuit accumulates switch closure events and converts the events into a linear increasing dc output. When the circuit accumulates it's maximum count the output resets to zero and starts the process over again.
