Yokogawa NFCP502‑W05 CPU Module | STARDOM FCN‑500 Autonomous Controller Spare

Description

Product Overview

Yokogawa NFCP502‑W05 is a high‑performance CPU module for Yokogawa STARDOM FCN‑500 autonomous controller. It combines DCS‑grade reliability and PLC‑style computing performance, equipped with Intel Atom industrial processor and ECC error‑correcting memory. Four independent Gigabit Ethernet ports, ESB/ER bus interface and SDHC data logging slot are integrated. It supports IEC61131‑3 programming standard and dual‑redundant bumpless transfer. This hardware is OEM obsolete. New surplus stock and fully‑tested refurbished spare parts are available for drop‑in replacement and maintenance of legacy FCN‑500 control systems in chemical, power and oil‑gas industries。
