Non-isolated Thermocouple and RTD Plug-in Modules – 2080-TC2 and 2080-RTD2 Appendix 3
It supports two- and three-wire type of RTD sensor wiring.
RTD Compatibility
An RTD consists of a temperature-sensing element connected by two, three, or
four wires that provide resistance input to the module. The following table lists
the RTD types that you can use with the module, including their temperature
range, accuracy, and ADC update rate.
Overrange and Underrange Conditions
If the channel temperature input is below the minimum value of its normal
temperature range for the represented sensor, the module reports an underrange
error through the Connected Components Workbench global variables. If the
channel temperature input is above the maximum value of its normal temperature
range for the represented sensor, an over-range error is flagged.
