Can anyone tell me if it's possible to use a 1762-IR4 input module to read resistance from a NTC thermistor (30K @ 25C)? I've been playing with input channel configurations all morning without success. maybe it just won't work.

I also have a 4-20mA module and a thermocouple module.

No, max resistance is 3000 ohms. See picture below.

Depending on your temperature range, I would replace the thermistor with a "RTD".
