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.
