PAGE 4 5 10 NOV 2006 MAN0235-09 ADC020/120 INPUT CONVERSION FACTOR The following table describes how real-world inputs are scaled into the controller. Given a known input current, the data value is configured by using the conversion factor from the table. The following formula is used: Data = Input Current (mA) / Conversion Factor Example: The user selects a current range of 0 to +20 mA: 1) The known input current is 14 mA..
