Product Overview: AAI143‑H00 S2
The AAI143‑H00 S2 is a rugged, high-density analog input module designed for use in Distributed Control Systems (DCS). It features 16 isolated channels, each accepting 4–20 mA field signals and equipped with HART digital communication capability. The S2 designation signifies enhanced sealing—specifically, dust and splash resistance—enabling reliable operation in tougher local environments such as control rooms adjacent to active process areas.

Applications
This module is suited for industrial automation systems requiring robust analog data acquisition. The S2 variant, with its protective gasketing and sealing, makes it ideal for installation in semi-exposed control panels—such as those in chemical processing zones or near mechanical equipment—where dust, airborne particulates, or incidental moisture are present.
