Product Description
The AAI543-H50/ATA4S-00 is a high-density analog output module for the Yokogawa CENTUM VP distributed control system (DCS). It provides 16 channels of 4–20 mA output, commonly used to drive pneumatic valve positioners, actuators, and variable speed drives.
This variant features the ATA4S-00 vertical pressure-clamp terminal interface, enabling organized, high-density wiring for compact control cabinets. Integrated HART digital communication allows the DCS to perform remote configuration, diagnostics, and monitoring of smart field actuators. The module uses a non-isolated (common return) architecture, maximizing output density without compromising signal accuracy or reliability.
