YOKOGAWA STARDOM FCN-RTU Autonomous Controller

 GENERAL

This document describes the general specifications of

the FCN-RTU low power autonomous controller with

NFCP050 CPU module.

For functions, refer to “FCN-RTU Low Power

Autonomous Controller Functions” (GS 34P02Q0201E).

 FEATURES

• High performance and low power consumption

modular controller

• Memory with ECC.

• FCN-RTU can be used wide temperature range and

high altitude place.

• Analog and digital I/Os adequate for gas/oil wellhead

control built in CPU module

• Four serial ports for plural communications built in

CPU module

• Up to eight additional I/O modules (with NFBU200)

• Wide voltage range (10 to 30 V DC input) power

supply module (NFPW426)

• Power supply module can be duplexed (NFBU200

with NFPW444)

• Low heat dissipation eliminates the need for a fan

• A wealth of RAS features — CPU self-diagnostics,

temperature monitoring, I/O diagnostics, and more

• Additional I/O modules (except CPU embedded I/Os)

hot-swappable

 CONFIGURATION

FCN-RTU consists of the following modules:

• Base module (NFBU050.NFBU200)

• Power supply module (NFPW426.NFPW444)

• CPU (with built-in I/Os) module (NFCP050)

Short type  (NFBU050)

F01E.ai

Long type  (NFBU200)

F01cE.ai

• Additional I/O modules (up to eight modules can be mounted on a base module)

There are two types of base module.

Short type : Configuration with a NFBU050 base module (short)

Long type : Configuration with a NFBU200 base module (long)

The following table shows a list of the functions of each configuration.

I/O MODULES

An autonomous controller FCN-RTU supports the following I/O modules and

up to eight of them can be installed on it.
