FAQ

Q: Can this module handle both current and voltage signals simultaneously? A: Each channel can be individually configured for either 4–20 mA current or 1–5 V voltage input, but not both simultaneously.

Q: How does this module differ from AAI135-S02? A: The S03 variant provides improved response time and higher channel-to-channel isolation for enhanced system reliability.

Q: What precautions are needed during installation? A: Ensure proper wiring, grounding, and signal type compliance. Avoid exceeding specified input ranges to maintain accuracy and prevent damage.
