Note7)
Note1) Use a 3-wire type RTD.
Note2) When exceeding the rated range, reference values which are not in the range of the conversion
accuracy assurance are indicated up to ±15 ° C. However, if the temperature drops (below -230
° C) or rise (over 900 ° C) more, the data will be the same value (K20000) as the one at the time of
disconnection.
Note3) The digital value will be K20001 from the Power-on to the converted data Ready (approx. 3
seconds) or when an error occurs (watchdog timer time-out error) on the microcomputer for the
RTD cassette. Take care of the use of the data during this period not to influence other programs.
Note4) From the disconnection to the recovery and converted data Ready (approx. 3 seconds), the
digital value will be K20001. Take care of the use of the data during this period not to influence
other programs.
Note5) The conversion speed is 200 ms or less regardless of the number of channels to be used.
And it will be reflected in the internal data register after the completion of a scan.
Note6) The full scale (F.S.) is -200 to 850 ° C for the accuracy range of RTD Pt100.
Note7) Each channel data is allocated as I/O data as the table below.

Note8) Supply power for 15 minutes or more after the power-on for performing the accurate
measurement before using the cassette.
