Current: 4 to 20 mA, 0 to 20 mA
Voltage: 1 to 5 V, 0 to 5 V, 0 to 10 V
The input type can be set individually for each input
Scaling (Voltage/Current Input)Voltage and current input data to be stored in the allocated words in the CIO area must be scaled (with the minimum and maximum values set by user) (4 points set separately)
Data Storage in the CIO AreaVoltage/Current Input:
The value derived from carrying out the following processing in order of the actual process data in the input range is stored in four digits hexadecimal (binary values) in the allocated words in the CIO Area.
1) Scaling →2) Zero/span adjustment → 3) Output limits
Temperature input:
The value derived from carrying out the following processing in order of the actual process data in the input range is stored in four digits hexadecimal (binary values) in the allocated words in the CIO Area.
1) ⁰C, °F conversion → 2) Zero/span adjustment → 3) Output limits
(temperatures are typically stored at 10 times the value)

*1. Square root calculation function is possible only during DC input. The square root is not extracted for temperature input. The square root calculation function is only available when the maximum scaling value is greater than the minimum scaling value. The square root is not extracted when the maximum scaling value is less than the minimum scaling value. When the square root function is used, set the scaling values after square root calculation (e.g., for flow rates or other values) for the process value scaling A and B settings.
*2. The cold junction compensation method specification function is available only for thermocouple inputs.
*3. The resistance thermometer input compensation function is only available for the resistance thermometer input.
