Product Overview: AAI143‑H50 /A4S10
The AAI143‑H50 /A4S10 is a 16‑channel isolated analog input module for industrial DCS systems. It supports multiple signal types—including 4–20 mA, 1–5 V, and thermocouples—and offers integrated HART communication (“H”) for advanced device diagnostics. The /A4S10 suffix indicates a pressure-clamp terminal block with surge absorber for robust signal protection.
