The NFBU200-S05 S2 is a base module manufactured by Yokogawa Electric Corporation for the FCN-500 (Field Control Node) autonomous controller family. It provides

 the structural backbone and electrical infrastructure to build modular industrial control systems by housing CPU, power supply, I/O, and communication

modules.A base module functions as the central chassis in a distributed control system (DCS) or modular PLC-like setup. It holds and

interconnects key functional modules, supports modular expansion, and enables system scalability and redundancy.

Frequently Asked Questions

1. What is the NFBU200-S05 S2 base module?

It is the backplane chassis for Yokogawa’s STARDOM FCN-500 automation system — housing and interconnecting CPU, power, and I/O modules to build a complete control unit.

2. What systems is it compatible with?

The NFBU200-S05 S2 works with STARDOM FCN-500 Field Control Node controllers and associated functional modules.

3. How many I/O modules can it support?

In standard control unit use, it supports up to about 8 I/O modules. With system extension units and appropriate

configuration, the overall system can support significantly more

modules across multiple units.
