15-2-2 Analog Output Signal Ranges
 4 to 20 mA
When the resolution is set to 1/6,000, the 4- to 20-mA range corresponds to hexadecimal values
0000 to 1770 (0 to 6,000). The entire data range is FED4 to 189C (-300 to 6,300).
Inputs between 3.2 and 4 mA are expressed as two’s complements. If the input falls below 3.2 mA,
open-circuit detection will activate and converted data will be 8000.
 -10 to 10 V Outputs
When the resolution is set to 1/6,000, the hexadecimal values F448 to 0BB8 (-3,000 to 3,000) corre-
spond to an analog voltage range of -10 to 10 V.
Specify a negative voltage as a two’s complement.
 0 to 10 V Outputs
When the resolution is set to 1/6,000, the hexadecimal values 0000 to 1770 (0 to 6,000) correspond
to an analog voltage range of 0 to 10 V.
Specify a negative voltage as a two’s complement.
