POINT
(1) Do not input an analog input current of more than ± 30 mA. A breakdown may
result due to overheating.
(2) Set the offset/gain values for the user setting range
the following conditions are satisfied.
{ (Gain value) – (Offset value) } > 5.5 mA
(3) When an analog value that exceeds the range of the digital output value
entered, the digital output value will be fixed at the maximum or minimum
value.
• For 0 to 4000, the range for the digital output value is from –96 to 4095.
