NFAI543-S51 S1 | Yokogawa | CENTUM VP 32-Ch AI Module

Product Description

High-Density Signal Processing for CENTUM VP

The Yokogawa NFAI543-S51 S1 is a high-density Analog Input (AI) module specifically engineered for the Field Control Station (FCS) subsystem of the Yokogawa CENTUM VP Distributed Control System. This module serves as a high-performance interface, capable of acquiring 16-bit high-resolution digital conversions from up to 32 independent analog channels. By consolidating a large number of inputs into a single plug-in unit, the NFAI543-S51 optimizes cabinet space and reduces system footprint in large-scale industrial installations.

Precision and Fault Tolerance

Designed for mission-critical reliability, the NFAI543-S51 S1 supports dual-redundant configurations, ensuring that signal acquisition continues uninterrupted even if a single module fails. It provides galvanic isolation between the field-side signals and the internal system bus, protecting the control logic from electrical surges and noise interference. With built-in advanced diagnostics, the module continuously monitors signal integrity, detecting open-circuit and short-circuit conditions to facilitate rapid maintenance and high process availability.
