8.5 SDM-A04 ANALOG OUTPUT
MULTIPLEXER TO STRIP CHART
This example illustrates the use of the SDM-
A04 4 Channel Analog Output Multiplexer to
output 4 analog voltages to strip chart.
While of questionable value because of current
r
equirements and strip chart reliability, some
archaic regulations require strip chart backup on
weather data. The SDM-A04 may be used with
the CR10 to provide analog outputs to strip charts.
The output values in this example are wind speed,
wind direction, air temperature, and solar radiation.
Instruction 103 is used to activate the SDM-
A04. T
he 4 millivolt values to output must be
stored in adjacent Input Storage locations, the
first of which is referenced in Instruction 103.
The following program measures the sensors
ever
y 5 seconds. The readings are moved to
another 4 locations and scaled to a 0 to 1000
millivolt output for the SDM-A04. Wind direction
is changed from a 0-360 degree input to output
representing 0 to 540 degrees. This conversion
is done in a subroutine which is described in the
next example.
The example also includes instructions to
output w
ind vector and average temperature
and solar radiation every hour.
