The Yokogawa AAI543-S00 is a high-performance analog input module designed for precise industrial data acquisition. It excels in converting analog signals (e.g., from sensors, transmitters) into digital data for Yokogawa DCS systems, ensuring reliable integration.

With stable signal processing, it delivers accurate measurements even in harsh industrial environments, supporting multiple input ranges to fit diverse application needs. Its compact design saves cabinet space, while easy installation and maintenance reduce operational downtime.

Ideal for process industries like oil, gas, and manufacturing, it enhances control system efficiency by providing real-time, trustworthy data for critical process monitoring and control.

*1: A dual-redundant configuration is enabled by using two identical modules with the same suffix codes.
*2: When AAI543-6/-F is installed in a node unit that conforms to the temperature environment, use it in the ambient 
temperature within 0 to 60 ºC range.
*3: When a switch over from control to stand-by module takes place in the dual-redundant configuration, the maximum period 
of time when the field output falls below 4 mA is 100 ms for AAI543-5/-E (standard switch-over response) and 2 ms 
for AAI543-6/-F (fast switch-over response). In case of connecting fast response type field devices, use AAI543
6/-F (fast switch-over response) in the dual-redundant configuration.
*4: When the dedicated cable is used, the withstanding voltage is 500 V AC (between the input signal and the system). When 
the ML connector cable is used, the withstanding voltage depends on the electrical specifications of the cable.
*5: When this module is installed in a ER bus node unit with HART function, the EB401 firmware must be rev. 2 or later
