Product Description
The NFAI141-S00 S1 (NFAI141) is a high-density analog input module designed for Yokogawa STARDOM autonomous controllers (FCN and FCJ). It provides 16 channels for isolated current or voltage measurement, enabling precise acquisition of field signals from sensors and transmitters.
Engineered for industrial automation, the NFAI141 supports standard signal ranges, including 4–20 mA and 1–5 V DC. Its compact form factor, robust Japanese engineering, and high noise immunity make it a reliable component for distributed control systems where signal accuracy and stability are critical.

Frequently Asked Questions
Does the NFAI141-S00 S1 support hot-swapping?
Yes, within the FCN-500 or FCJ system, the NFAI141 can be replaced while the controller is powered, provided the system configuration allows online maintenance.
Can I mix voltage and current inputs on the same module?
The module supports both 4–20 mA and 1–5 V signals, but the input type must match the wiring and STARDOM software configuration. Proper shunt resistors or wiring schemes must be used according to the Yokogawa technical manual to prevent signal interference.
