INTRODUCTION

The Wind Line Driver converts raw signals from Wind Monitor-HD
sensor to proportional 4 to 20 mA current loop values. The Line Driver
acts like a variable resistance that draws 4 - 20 mA when powered
with 12 to 30 VDC. Although it has only one PC board, the Line Driver
contains two completely independent circuits - one for wind speed
and the other for wind direction. See wiring diagram.

IMPORTANT!
The Wind Line Driver provides a calibrated current signal
for wind speed and wind direction. Externally connected
devices should be reviewed for compatibility and correct
signal scaling.

Repairs should be attempted only by qualifi ed service personnel.
