Product Description
RAK12022 is a PT100 IO module that uses MAX31865, an easy-to-use resistance-to-digital converter optimized for platinum resistance temperature detectors (RTDs). An external resistor sets the sensitivity for the RTD being used and a precision delta-sigma ADC converts the ratio of the RTD resistance to the reference resistance into digital form. The MAX31865’s inputs are protected against overvoltage faults as large as 45 V. Programmable detection of RTD and cable open and short conditions is included.
