Pin Assignment and Wiring Guide
The following is the 85M-38XX-T modules pin assignment and wiring guide.
Analog Input Data Format
The I/O analog inputs have a 16-bit, unipolar, and analog to digital (A/D) converter that measures input
voltages from 010 V and current from 4–20 mA (with Burnout). The following chart is the raw data conversion
table for current and voltage.
The voltage ranges from 0 to 10 V. The lowest voltage of 0 V represents raw data of 0, and the highest voltage
of 10 V represents raw data of 65535. When the raw voltage data is at 1, it represents 0.15 mV. The current
ranges from 0 to 20mA. The lowest current of 0 mA represents a raw data value of 0. Users can manually adjust
the burnout value from 0 to 4 mA. All raw data below the burnout value will be 0. The highest current of 20 mA
represents raw data of 65535. Raw current data of 1 represents 0.3125 µA.
Burnout mode can indicate if the current analog input has burned out.
NOTE
P
lease refer to the ioPAC RTU Software User’s Manual for the burnout mode settings.
NOTE
Grounding the device through the earth/ground pin (
) gives 6kV ESD protection.
