How do you connect RTD to PLC?

To connect a Resistance Temperature Detector (RTD) to a Programmable Logic Controller (PLC), you typically use an RTD input module designed for the PLC. The RTD's resistance values are converted to a corresponding temperature reading by the module, which then communicates this data to the PLC. Ensure proper wiring according to the RTD type (2-wire, 3-wire, or 4-wire) and configure the PLC's software to interpret the input correctly. Calibration may also be necessary to ensure accurate temperature readings.
