3 SPECIFICATIONS
3 - 8
POINT
(1) Set within the analog input range and digital output range for each input
range.
If these ranges are exceeded, the maximum resolution and accuracy may not
fall within the performance specifications. (Avoid using the dotted line area
shown in Figures 3.3 and 3.4.)
(2) When inputting an analog current out of the range between -30mA to 30mA,
the elements may be damaged.
(3) Set the offset/gain values for the user range setting
the following conditions are met.
(a) Offset value, gain value setting range: -20.0 to 20.0mA
(b) Choose either one of the following formulas, which corresponds to the
resolution mode to be set.
1) Normal resolution mode: { (Gain value) - (Offset value) } > 5.5mA
2) High resolution mode: { (Gain value) - (Offset value) } ≥ 16.0mA
(4) When an analog value that exceeds the range of Digital output value
entered, Digital output value will be fixed at the maximum or minimum value.
