Constant) on module response to a temperature change.

5 ANALOG 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 ±20mA:

1. The known input current is 14mA.

2. Using the table, the conversion factor for the current range of ±20mA is 0.000625.

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

Data = Input Current (mA) / Conversion Factor

22400 = 14mA / 0.000625
