Thermistor settings
When
NTC Thermistor
is selected as
Signal Type
for the FC6A-J8CU1 or FC6A-J8CU4, the following parameters
must be set.
The characteristic of NTC Thermistor is 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.

Data
Data refers to the input analog values converted to digital values at the interval of the sampling time.
The data is not guaranteed when the
Satus
is a value other than "0". For details on when
PTC Thermistor
(threshold) is selected as
Signal Type
, refer to “ PTC Thermistor (Threshold)” on page 30-21.
*1 When the
Sampling Time
is set to 30 milliseconds, 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 milliseconds.
*2 Information are described in the instruction sheet for the thermistor to use.
