Note An internal signal is connected to the RSV terminal to dissipate heat. Do not
wire the RSV terminal.
The digital values that are output are converted to analog data according to
the output range used, as shown below. When the value exceeds the output
range, the DA conversion data is fixed at the High Limit or Low Limit set value.
The values 0000 to 1770 hex (0 to 6,000) correspond to the voltage range 0 to
5 V. The output range is
