Product Description
The NFAI143 is a high-performance analog input module for Yokogawa FIO systems, widely used in CENTUM VP and CS 3000 architectures. It receives 16 channels of 4–20 mA DC signals from field transmitters such as pressure, flow, and temperature sensors.
The NFAI143 (Model: NFAI143) incorporates robust system-to-field isolation, ensuring that electrical interference from the field does not affect the control system backplane, maintaining signal integrity for mission-critical applications.

Operational Environment
The NFAI143 is designed for continuous industrial operation. In redundant configurations, it supports hot-swapping (Online Module Replacement), enabling maintenance without shutting down the Field Control Station (FCS).
It is compatible with pressure-clamp terminal blocks or MIL connector cabling, allowing flexible marshalling according to the cabinet installation standard.
Frequently Asked Questions
Does the NFAI143 support HART communication?
No. The standard NFAI143 is analog-only. For HART-enabled inputs, use the NFAI143-H or AAI143 modules.
What terminal blocks are recommended?
The module typically interfaces with pressure-clamp terminals (e.g., NFTB412) or MIL connector cables, depending on cabinet wiring standards.
