XGB Analog edition manual
The conversion speed of XGF-RD4A is 40 ms per channel and each channel is converted
sequentially, that is, one channel is converted and then the next channel is converted.
(Run/stop can be specified independently for each channel.)
The conversion speed includes the time to convert input temperature (resistance value) to digital
value and to save the converted digital data into the internal memory.
∴ Processing time = 40ms X Number of the using channels
[Example] 3 channels are used: Processing time = 40ms X 3 = 120ms
The accuracy of RTD module is described below.
• When the ambient temperature is 25 ± 5℃: within ±0.3% of available input range
• When the ambient temperature is 0 to 55℃: within ±0.5% of available input range
Example) PT100 is used and the ambient temperature is normal.
To measure 100℃, the conversion data output range:
100℃ - [ { 600 - (-200) } x 0.3 % ] ~ 100℃ + [ { 600 - (-200) } x 0.3 % ]
Namely, 97.6 ~ 102.4 [℃]
(1) The input temperature is converted to digital value down to the one decimal place.
Ex.) If the detected temperature is 123.4℃, its converted value to be saved to the internal
memory will be 1234.
(2) Temperature can be converted to Celsius or Fahrenheit scale temperature value as desired.
Ex) If Pt100 sensor is used, the temperature of 100.0℃ can be converted to 2120 when
Fahrenheit scale is used.
• Conversion ℃ to ℉,
• Conversion ℉ to ℃,
(3) Maximum temperature input range is higher/lower within 10℃ than regular temperature input
range. However, the precision will not be guaranteed for any temperature out of regular
temperature input range.
Maximum temperature input ranges of sensor are as follows;
• PT100 : -210.0 ~ 610.0℃
• JPT100 : -210.0 ~ 610.0℃
