input value
= input voltage(V)
10.5V
32,767
The Input Value is the decimal value of the word in the
input image for the corresponding analog input.
For example, if an input value of 16,021 is in the input image,
the calculated value is:
10.5V
32,767
16,201 = 5.1915(V)
It should be noted that the actual value may vary within the
accuracy limitations of the module.
To determine an approximate current that an input value represents, you can use the
following equation:
input value
= input current (mA)
2
1 mA
32,767
The Input Value is the decimal value of the word in the
input image for the corresponding analog input.
For example, if an input value of 4096 is in the input image,
the calculated value is:
4096 = 2.625 (mA)
It should be noted that the actual value may vary within
the accuracy limitations of the module.
21 mA

Converting Analog Output Data
Use the following equation to determine the decimal value for the current output:
[Desired Current Output (mA) – 4 mA] = Output Decimal Value
For example, if an output value of 8 mA is desired, the value to be put in the
corresponding word in the output image can be calculated as follows:
(8 mA – 4 mA) = 8192
32,767
16 mA

16 mA
Use the following equation to determine the decimal value for the voltage output:
32,767
Desired Voltage Output (V dc) = Output Decimal Value
For example, if an output value of 1V dc is desired, the value to be put in the
corresponding word in the output image can be calculated as follows:
1V dc = 3277
