PERFORMANCE
Conversion accuracy: Refer to the table at the end of this section.
The resolution and conversion accuracy are defined against the potentiometer's total resistance.  If the actual resistance range (between the zero and span positions) is narrower than the total resistance, the values change in proportion.  Using at least 50 % of the total resistance is basically recommended.
Conversion rate: 80 / 40 / 20 / 10 msec. selectable
Data range: 0 – 10000
Data allocation: 4
Current consumption: Approx. 50 mA
Temp. coefficient: ±0.015 % /°C
Temperature coefficient is defined against the potentiometer's total resistance. If the actual resistance range (between the zero and span positions) is narrower than the total resistance, the values change in proportion. Using at least 50 % of the total resistance is basically recommended.
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength: 2000 V AC @ 1 minute (input 1 to input 2 to input 3 to input 4 to internal bus or internal power)
2000 V AC @ 1 minute (power input to FG; isolated on the power supply module)
