AAI543-H00 Analog Output Module

The Yokogawa AAI543-H00 is a 16-channel isolated analog output module designed for the CENTUM VP, CENTUM CS 3000, and ProSafe-RS distributed control systems (DCS). Its core function is to convert digital control signals from the DCS controller into precise 4–20 mA DC analog output signals to drive final control elements such as control valves, actuators, and positioners. The "H" designation indicates integrated HART digital communication capability, enabling remote configuration and diagnostics of smart field devices over the same wiring.
