Interface #40 to Voltage, #SI5100
Interface the 40C Anemometer with an analog device such as a computer, meter, or recorder.
Details
The SI5100 wind speed interface module is used for interfacing the NRG 40C Anemometer to an analog device such as a computer, meter, or recorder.
The module output signal is a negative ground voltage set at 0 to 5 VDC at wind speeds ranging from 0 to 44.7 m/s (0 to 100 mph).
Power is supplied by any 12 VDC source. The SI5100 is packaged in a plastic case with an octal plug. A DIN-rail mountable octal socket with screw terminals is included.
