POINT
(1) Do not input an analog input voltage of more than ± 15 V. The input elements
may be damaged.
(2) Set the offset/gain values for the user setting range
the following conditions are satisfied.
{ (Gain value) – (Offset value) } > 1.5 V
(3) When an analog value that exceeds the range for 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.
• For –4000 to 4000, the range for the digital output value is from –4096 to 4095.
