Internal Circuits
Wiring
Connect the terminals of the Analog Input Unit for each Input Unit according
to the following diagrams, depending on whether a voltage input or a current
input is being used.
Note
Do not wire the RSV terminal. This terminal is used to connect an internal sig-
nal for heat radiation.
Input Range and
Conversion Data
The analog data that is input will be converted to digital data according to the
input range, as described here. If the input exceeds the input range, the AD
conversion data will be fixed at the upper or lower limit.
■
Input Range: 0 to 5 V
The voltage range 0 to 5 V corresponds to 0000 to 1770 hex (0 to 6,000). The
convertible data range is FED4 to 189C hex (
–
300 to 6,300). Negative volt-
