Voltage in the -10 to 10 V
range corresponds to hexa-
decimal values F448 to 0BB8
(-3,000 to 3,000). The range
of data that can be converted
is F31C to 0CE4 hex (-3,300
to 3,300). A negative voltage
is expressed as two’s comple-
ment.
Voltage in the 0 to 10 V range
corresponds to hexadecimal
values 0000 to 1770 (0 to
6,000). The range of data that
can be converted is FED4 to
189C hex (-300 to 6,300). A
negative voltage is expressed
as two’s complement.
Voltage in the 0 to 5 V range
corresponds to hexadecimal
values 0000 to 1770 (0 to
6,000). The range of data that
can be converted is FED4 to
189C hex (-300 to 6,300). A
negative voltage is expressed
as two’s complement.
Voltage in the 1 to 5 V range
corresponds to hexadecimal
values 0000 to 1770 (0 to
6,000). The range of data that
can be converted is FED4 to
189C hex (-300 to 6,300).
Voltage in the range of 0.8 to
1 V is expressed as two’s
complement.
If an input is below the range
(i.e., less than 0.8 V), the
open-circuit detection func-
tion is activated and the data
becomes 8,000.
