C-Series Module, RTD

RTD input modules measure temperature using resistance temperature detectors (RTDs), which provide highly accurate and stable readings.

Important specs include RTD wiring support (2-, 3-, or 4-wire), accuracy, and supported sensor ranges. RTD modules are typically more accurate but cover narrower temperature ranges than thermocouple modules.

These modules are preferred in lab environments or industrial systems where accuracy and stability are more critical than extreme range. They're often used in quality control, material testing, and precision process monitoring.
