Declaration of Conformity

Model 05631C Wind Line Driver

The undersigned hereby declares on behalf of R. M.
Young Company that the above-referenced product, to
which this declaration relates, is in conformity with the
provisions of:

Council Directive 2004/108/EC (December 15, 2004)
on Electromagnetic Compatibility

The Wind Line Driver converts raw signals from the wind sensors 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 below.

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

Repairs should be attempted only by qualied service personnel.

CALIBRATION FORMULAS

WIND SPEED vs mA OUTPUT

m/s = ( 6.250 x mA)-25
knots = (12.149 x mA)-48.6
mph = (13.980 x mA)-56
km/h = (22.500 x mA)-90

WIND DIRECTION vs mA OUTPUT
DEGREES = (22.5 x mA)-90
