    Ro

    The RTD resistance at 0 degrees Celsius.

    Default: 100 Ω

    datatype_icon

    voltage

    The voltage read from the RTD.

    This input supports waveform and double-precision, floating-point data types.

    datatype_icon

    Iex

    The excitation current used with the RTD.

    Default: 0.15 µA

    datatype_icon

    A

    A coefficient of the Callendar Van-Dusen equation that fits your RTD.

    Default: 0.00390802 — Represents the coefficient for the European curve (also called the DIN 43760 standard).

    datatype_icon

    B

    A coefficient of the Callendar Van-Dusen equation that fits your RTD.

    Default: -5.80195E-07 — Represents the coefficient for the European curve (also called the DIN 43760 standard).

    datatype_icon

    temperature

    The return temperature value in degrees Celsius.

    This output returns a waveform or double-precision, floating-point data type depending on the data type of the voltage input.
