4. Functionality
The 5B34-04 module functions as a precision signal conditioner that converts the resistance change of a Pt100 RTD sensor into a linearized voltage output. The module excites the RTD with a stable current source, measures the resulting voltage drop across the sensor, and applies internal linearization circuitry to produce a voltage output directly proportional to temperature.
Operating Principle:
1. The RTD sensor changes resistance with temperature.
2. The module’s excitation current passes through the RTD, generating a voltage proportional to resistance.
3. Internal circuitry linearizes the signal according to the Pt100 temperature-resistance curve.
4. The conditioned signal is amplified and scaled to a 0–5 V output corresponding to 0–600°C.
5. The output is galvanically isolated from the input and power supply, ensuring signal integrity.
