Why Engineers Specify This Model
- High-Resolution 16-bit ADC: Delivers ±0.1% full-scale accuracy, meeting the precision demands of custody-transfer metering and safety-critical loops.
- Dual-Mode Input (mA / V): A single module handles both 4–20 mA transmitters and 1–5 V sensors, reducing spare-part SKU count and simplifying panel design.
- Full Galvanic Isolation: Eliminates ground-loop interference in multi-drop field wiring — essential for long cable runs in oil & gas and utility installations.
- Native STARDOM Integration: Plug-and-play slot compatibility with FCN/FCJ base units; no external signal conditioners or marshalling panels required.
- Compact Form Factor: Maximizes I/O density in space-constrained RTU enclosures and offshore junction boxes.
- Long Product Lifecycle: YOKOGAWA’s commitment to 10+ year parts availability reduces lifecycle cost and obsolescence risk for long-horizon plant projects.

Application-Specific FAQ
Q: Is the NFAI141-S00 compatible with YOKOGAWA CENTUM VP or ProSafe-RS?
A: No. The NFAI141-S00 is designed exclusively for the STARDOM FCN/FCJ platform. For CENTUM VP, specify the AAI141-S00 or AAI143-S00 series. For ProSafe-RS, consult the SCP400 I/O module lineup.
Q: Can this module accept HART signals from smart transmitters?
A: The NFAI141-S00 passes the 4–20 mA analog signal; native HART digital communication requires a HART multiplexer or a HART-enabled variant. Confirm with your YOKOGAWA system integrator.
Q: What is the maximum cable length for field wiring?
A: YOKOGAWA recommends shielded twisted-pair cable with a maximum loop resistance of 600 Ω for 4–20 mA inputs. Practical cable runs of 300–500 m are typical in plant environments.
Q: Is this module suitable for SIL-rated safety loops?
A: The NFAI141-S00 is a standard (non-SIL) module. For IEC 61511 safety instrumented systems, use YOKOGAWA ProSafe-RS SIL-certified I/O modules.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. A CoC is available upon request for all units. Contact support@konmask.com before placing your order if CoC is a project requirement.
