■
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).
■
Input Range: 0 to 20 mA
The current range 0 to 20 mA corresponds to 0000 to 1770 hex (0 to 6,000).
The convertible data range is FED4 to 189C hex (
–
300 to 6,300). Negative
currents are expressed as two’s complements (16 bits). When a disconnec-
tion occurs, the data equivalent to 0 mA input will be used (0000 hex).
