1OK Thermistors
The SCADA 3000 is compatible with 10K thermistors that match the curve data listed in the
tables in Appendix C. The monitoring temperature range of the 10K thermistor is -80 to
300ºF (-62º to 149ºC). Thermistors can be connected directly to the input terminals without
regard for polarity. Choose an input and connect the wires to the corresponding screw termi-
nals for that input. The configuration jumper should be set to the TMP/DRY position. The
figure below shows how to connect a thermistor sensor:
