Product Overview

NFBU200‑S05 is a rack‑mount base module for Yokogawa FCN‑RTU autonomous remote controller systems. It provides mechanical mounting and high‑speed backplane bus communication for CPU and I/O modules, supporting up to eight expansion I/O cards for remote field‑site data acquisition. Built‑in comprehensive RAS diagnostic functions monitor hardware health continuously. It supports both 19‑inch cabinet rack‑mount and DIN‑rail mounting for flexible field‑cabinet deployment. OEM production discontinued; available as refurbished and new‑old‑stock spare‑parts for remote monitoring‑system overhaul and site‑maintenance projects.

Application Notes

‑ Exclusively for FCN‑RTU system hardware; verify mechanical fit and firmware compatibility before replacement. ‑ Install inside ventilated industrial cabinet; avoid dust accumulation and condensation. ‑ Observe strict ESD anti‑static precautions during module installation. ‑ Typical deployment: oil‑gas remote‑site monitoring, pipeline‑monitoring, water‑treatment remote‑I/O cabinets for Yokogawa FCN‑RTU spare‑part stocking.
