The B872 accepts data values ranging from 0000 to 4095 and converts them into output voltages for all four ranges. The output voltage is directly proportional to the data value. The figure below is a data value to output conversion chart for the B872-200 module.
Calculations for determining voltage reading or data value for 0 to 5 V or 0 to 10 V ranges:
To solve for voltage reading:
where the total voltage span is the sum from lowest to highest voltage in the selected range. If the range is -10 to +10 V, the total voltage span is 20 V.
Calculations for determining voltage reading or data value for -5 to 5 V or -10 to 10 V Ranges:
To solve for voltage output:
where offset voltage is the lower number in the selected range. If the range is -10 to +10 V, the offset voltage is -10 V.
Examples:
-5 to 5 V = 10 V
Examples:
-5 to 5 V = -5 V
