Product Overview: Yokogawa AAI143‑H50 S1
The AAI143‑H50 S1 is a 16-channel isolated analog input module with integrated HART communication protocol. It supports not only the standard 4–20 mA signal but also other analog types like 1–5 V and thermocouples. Designed for precision, reliability, and seamless integration into industrial Distributed Control Systems (DCS), it features pressure-clamp terminals, hot-swappable capability, and strong noise immunity.
