-10 to 10 V Inputs
Voltages in the -10 to 10 V range correspond to
hexadecimal 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 a two’s complement.
0 to 10 V Inputs
Voltages in the 0 to 10 V range correspond 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 a two’s complement.
0 to 5 V Inputs
Voltages in the 0 to 5 V range correspond 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 a two’s complement.
1 to 5 V Inputs
Voltages in the 1 to 5 V range correspond to hexa-
decimal 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 a two’s complement.
If an input is below the range (i.e., less than 0.8 V),
the open-circuit detection function is activated and
the data becomes 8,000.
