6 ANALOG CONVERSION OUTPUT FACTOR

The following table describes how program data values are scaled to real-world analog voltage outputs by

the module. Given a desired output current, the data value is converted by using the conversion factor

from the table. The following formula is used: Data = Output Current (mA) / Conversion Factor

Example: The user selects a current range of ±20mA:

1. The desired output current is 12mA.

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

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

Data = Output Current (mA) / Conversion Factor

19200 = 12mA / 0.000625
