4 to 20 mA
The current range 4 to 20 mA corresponds to hexadecimal values 0000 to
1770 (0 to 6,000 decimal). The range of data that can be converted is FED4 to
189C (–300 to 6,300 decimal). Negative voltages are expressed as two’s
complements. Inputs of 3.2 to 4 mA are expressed as two’s complements.
When the input level drops below the input range (input is less than 3.2 mA), a
line disconnection is detected, and the data is returned as 8,000.
Analog Output Signal Ranges
–10 to 10 V
Hexadecimal values F448 to 0BB8 (–3,000 to 3,300 decimal) correspond to
the voltage range –10 to 10 V. The output range is –11 to 11 V. When
outputting negative values, specify the DA conversion data as its two’s
complement.
0 to 10 V
Hexadecimal values 0000 to 1770 (0 to 6,000 decimal) correspond to the volt-
age range 0 to 10 V. The output range is –0.5 to 10.5 V. When outputting neg-
ative values, specify the DA conversion data as its two’s complement.
