Product Introduction – Yokogawa AAI543-H00/K4S00
The Yokogawa AAI543-H00/K4S00 is a high-precision analog output module designed for complex industrial automation and process control systems. Part of the AAI543 series, this module offers 16 independent, isolated 4–20 mA analog output channels, designed to interface between digital control systems (such as DCS or PLC) and field devices like valves, actuators, and converters.
The K4S00 suffix indicates a specific configuration of the terminal block: a removable terminal structure, enhancing installation flexibility, especially for applications requiring frequent maintenance or modular replacement. Combined with its electrical isolation and high update rate, this module is ideal for high-performance, high-reliability applications.
