During commissioning, the Pt100 probe is ready. The PLC input requires 4…20 mA.
The team also checks who supplies power to the loop.
Hypothetical scenario: temperature measurement is added to an existing control panel. The electrician follows the wiring diagram, while the automation engineer confirms the input type and range in the PLC.
For this connection, the PR 3331 converter from PR electronics:
• converts the Pt100 signal into a passive 4…20 mA signal, powered by the loop;
• galvanically isolates the sensor circuit from the output loop;
• allows local selection of the precalibrated range using DIP switches.
Before testing, the team checks the loop power supply, the connected load and matching scaling in the converter and PLC. The passive output requires a powered loop.
What mismatch have you encountered when connecting a temperature converter, and which check clarified it?
