Analog Input Units Section 7-2
When the resolution is 1/12,000, the 0 to 5 V range corresponds to hexadeci-
mal 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 corresponds to hexadeci-
mal 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
function is activated and the data becomes 8,000.
When the resolution is 1/12,000, the 1 to 5 V range corresponds to hexadeci-
mal 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.
