â– Input Range:1 to 5 V
The voltage range 1 to 5 V corresponds to 0000 to 1770 hex (0 to 6,000). The
convertible data range is FED4 to 189C hex (
–300 to 6,300). If a the input volt-
age falls below the input range (input voltage less than 0.76 V), a disconnec-
tion is detected and the data is set to 7FFF hex.
â– Input Range: 0 to 10 V
The voltage range 0 to 10 V corresponds to 0000 to 1770 hex (0 to 6,000).
The convertible data range is FED4 to 189C hex (
–300 to 6,300). Negative
voltages are expressed as two’s complements (16 bits). When a disconnec-
tion occurs, the data equivalent to 0 V input will be used (0000 hex).
â– Input Range:
–10 to 10 V
The voltage range –10 to 10 V corresponds to F448 to 0BB8 hex (–3,000 to
3,000). The convertible data range is F31C to 0CE4 hex (
–3,300 to 3,300).
Negative voltages are expressed as two’s complements (16 bits). When a dis-
connection occurs, the data equivalent to 0 V input will be used (0000 hex).
