Conversion speed
The conversion speed of 2MLF-RD4A is 40ms per channel and each channel is
converted sequentially, that is, channels are converted one after another. 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 channels used
Example: If three channels are used: Processing time = 40ms X 3 = 120ms
Accuracy
The accuracy of RTD module is dependent on the ambient temperature.
