Yokogawa AAI543-H61 Analog Output HART Module

Feature & Principle

It receives digital control commands from the DCS controller, converts them into isolated 4-20mA analog output signals, superimposed with HART digital signal for instrument remote parameter setting and diagnosis. It supports channel open circuit detection and redundant hot swap configuration, provides stable regulating output for flow, pressure and temperature closed-loop control loops.
