Product Description
The AAI543-H00/A4S00 is a high-density analog output module for the Yokogawa CENTUM VP DCS. It provides 16 channels of 4–20 mA output, specifically designed to drive control valves, actuators, and other final control elements.
Equipped with the A4S00 interface, this module connects directly to pressure-clamp terminal boards (ATA4S/ATA4D). The H suffix indicates HART digital communication support, enabling remote diagnostics, maintenance data retrieval, and predictive valve monitoring. Its non-isolated, 16-channel architecture maximizes slot efficiency in large-scale automation applications.
