Yokogawa AAI543-H50 Analog Output Module

Feature & Principle

It is an isolated analog output module for Yokogawa CENTUM VP DCS system. It converts digital control signals from the controller into 4-20mA DC analog signals to drive field transmitters, valves and actuators. It supports HART protocol communication, each channel is isolated, with high output accuracy and open circuit detection function for field loop monitoring.
