FAQ (Q&A)

Q1: What is the maximum cable length for analog inputs?
A1: For optimal performance, use shielded cables ≤ 100m. Beyond this, signal degradation may occur.

Q2: Can the module operate in high-humidity environments?
A2: Yes, it complies with IEC 60721-3-3 Class 3H3 (humidity ≤ 95% non-condensing).

Q3: Is software required for configuration?
A3: Basic settings use DIP switches, but ABB’s Automation Builder software enables advanced tuning.

Q4: What is the module’s MTBF (Mean Time Between Failures)?
A4: Approximately 150,000 hours under standard operating conditions.

Q5: Are spare terminals included for daisy-chaining power?
A5: Yes, the module has auxiliary terminals for power loop-through.

Q6: Does it support HART communication?
A6: No, the 07AI91 does not support HART. For HART, consider the 07AI95 model.
