FREQUENTLY ASKED QUESTIONS

Technical Specifications:

Q: What are the two primary resistance ranges configurable for the RTD channels?

A: The configurable resistance ranges for each channel are 0 to 500 ohms or 0 to 3000 ohms.

Wiring & Installation:

Q: Is an external power supply required for the RTD excitation current on the module?

A: No, the module provides the necessary excitation current internally when configured for the specific RTD type.

Troubleshooting & Compatibility:

Q: What types of faults and diagnostic alarms does the module report?

A: It reports open RTD, input short, under/over range, and high/low alarm conditions.

Replacement & Upgrades:

Q: What is the rated accuracy for resistance or temperature measurement at 25 degrees C?

A: The accuracy is plus/minus 0.15 percent on both resistance and RTD temperature measurement.
