(5) Sampling Time
Analog values are converted to digital values at the interval of the sampling time. Depending on the analog I/O module, you may
be able to change the sampling time setting.
(6) Thermistor settings
When NTC thermistor is selected for the FC6A-J8CU1/FC6A-J8CU4 signal type, the following parameters must be set.
*1 Information are described in the instruction sheet for the thermistor to use.
The characteristic of NTC thermistor is that the resistance decreases as the temperature rises. The analog modules measure the
resistance of the thermistor and calculate the temperature based on above three parameters.
The measurable range of the resistance of NTC thermistor is 100 Ω to 200,000 Ω. The range of temperature that can be calculated
is -90°C to 150°C. Select NTC thermistor that functions within those ranges.

*1 When the sampling time is set to 30 ms, the modules may be more easily affected by commercial power supply noise (50/60 Hz noise)
and fluctuations in input values may become larger. If there are large fluctuations in input values, change the sampling time to 120 ms.
