Product Overview: AAI143‑H03 S1
The AAI143‑H03 S1 is a precision analog input module designed for Distributed Control Systems (DCS). It provides 16 isolated 4–20 mA input channels with built-in HART communication. The “H03” suffix indicates the inclusion of HART protocol plus the ISA G3 and widened temperature range (−20 °C to +70 °C), while “S1” denotes the standard module variant. Compact and robust, it’s ideal for demanding industrial environments.
