The Yokogawa AAI143‑H00/A4S10 is a precision, isolated analog input module built for industrial Distributed Control Systems (DCS) such as CENTUM VP. It features 16 fully isolated input channels configurable for multiple signal ranges (e.g., 0–20 mA, 4–20 mA, 0–10 V). Integrated HART communication enables diagnostics and parameter adjustments, and the A4S10 suffix denotes an analog pressure clamp terminal block with built-in surge absorber for enhanced signal protection.
