Product Description
The NFAI543-S50/A4S00 is a high-density analog output module designed for seamless integration into Yokogawa CENTUM VP and STARDOM FCN/FCJ control systems. It provides precise current outputs for complex industrial processes, featuring 16 fully isolated channels, each delivering stable 4–20 mA signals. The module architecture emphasizes signal integrity and galvanic isolation, protecting sensitive system components from ground loops and electrical noise.
With an accuracy of ±0.3% of full scale and a 10 ms response time, the NFAI543-S50/A4S00 is optimized for high-speed, dynamic control loops. Its rugged construction and wide operating temperature range ensure reliable performance in mission-critical environments, including petrochemical, power generation, and advanced manufacturing applications.

Technical FAQ
What does the "A4S00" suffix mean?
The A4S00 identifies the terminal board interface and configuration options, ensuring proper connection to Yokogawa cabinet field wiring blocks.
Does the NFAI543 require external loop power?
Yes. Each of the 16 output channels requires an adequate external power supply to drive the 4–20 mA current loops. Consult the installation manual to verify that the power source meets the load requirements of the connected field devices.
