5 INPUT CONVERSION FACTOR

The following table describes how real-world inputs are scaled into the controller. Given a known input

voltage, the data value is configured by using the conversion factor from the table. The following formula

is used:

Data = Voltage In (Vin) / Conversion Factor

Example: The user selects a voltage range of 0 to +5 VDC:

1) The known input voltage is 3 VDC.

2) Using the table, the conversion factor for the voltage range of 0 to +5 VDC is .00015625.

3) To determine the data value, the formula is used:

Data = Vin / Conversion Factor

19200 = 3 VDC / 0.00015625
