0 to 5 V Inputs
When the resolution is 1/6,000, 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.
When the resolution is 1/12,000, the 0 to 5 V range
correspond to hexadecimal values 0000 to 2EE0 (0
to 12,000). The entire data range is FDA8 to 3138
hex (-600 to 12,600). A negative voltage is
expressed as a two’s complement.
1 to 5 V Inputs
When the resolution is 1/6,000, the 1 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).Voltage in the
range of 0.8 to 1 V is expressed as a two’s comple-
ment.
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.
When the resolution is 1/12,000, the 1 to 5 V range
correspond to hexadecimal values 0000 to 2EE0 (0
to 12,000). The entire data range is FDA8 to 3138
hex (-600 to 12,600). 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 function is activated and
the data becomes 8,000.
0 to 20 mA Inputs
When the resolution is 1/6,000, the 0 to 20 mA
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 current is expressed as a two’s comple-
ment.
