YOKOGAWA NFAI135-S01 Analog Input Module – CENTUM VP Field Control Station
When an analog input module fails in a live DCS environment, the consequences are immediate and severe: process variables go blind, operators lose visibility into critical field signals, and safety interlocks may trip the entire unit. In continuous-process industries — refining, petrochemicals, power generation — even minutes of lost analog data can cascade into unplanned shutdowns costing tens of thousands of dollars per hour. The YOKOGAWA NFAI135-S01 is the precision component that keeps those signals flowing reliably, 24/7.
The NFAI135-S01 occupies a pivotal position within YOKOGAWA’s CENTUM VP Field Control Station (FCS) architecture. As a 16-channel analog input module engineered to YOKOGAWA’s exacting IEC and ISA standards, it represents the front line of process data acquisition in one of the world’s most trusted DCS platforms — a platform deployed across thousands of critical facilities globally. Its combination of high channel density, galvanic isolation, and seamless integration with the CENTUM VP I/O bus makes it a benchmark component in modern industrial automation.

Frequently Asked Questions
Q: Is the NFAI135-S01 compatible with CENTUM CS 3000?
A: The NFAI135-S01 is designed for the CENTUM VP platform. While some CENTUM CS 3000 and CENTUM VP I/O modules share physical form factors, cross-platform compatibility must be verified against your specific FCU and node unit revision. Contact us for a compatibility check before ordering.
Q: Do you supply new or refurbished units?
A: We supply both new (factory-sealed) and professionally refurbished units depending on availability. Stock condition is clearly stated in your quotation. All units pass our QA inspection regardless of condition.
Q: What is the lead time for the NFAI135-S01?
A: Lead time varies by stock availability. In-stock units typically ship within 2–5 business days. For out-of-stock items, lead time is quoted individually — typically 2–6 weeks depending on sourcing.
Q: Can you provide a Certificate of Origin or other export documents?
A: Yes. We provide commercial invoice, packing list, and Certificate of Origin (COO) as standard. Additional documents (e.g., MSDS, test reports) are available upon request.
Q: What warranty do you offer?
A: We offer a 90-day warranty against defects in materials and workmanship on all units. Extended warranty options are available — please inquire at the time of order.
Q: Can I return a module if it doesn’t fit my system?
