Yokogawa NFBU200 Base Module

Product Introduction

The Yokogawa NFBU200 Base Module is a fundamental component in the ProSafe-RS Safety Instrumented System (SIS) platform. Serving as the backbone of the control rack, it provides essential mechanical support and electrical connections for various safety input and output modules. The base module acts as a communication and power distribution hub, enabling reliable signal transfer and power supply to connected field I/O modules.

Designed for robustness and long-term reliability, the NFBU200 ensures optimal system integrity under harsh industrial environments. Its modular design supports quick installation and maintenance, reducing downtime and facilitating scalable system expansion. The NFBU200 is a key enabler for constructing flexible, scalable, and highly reliable safety systems in industries such as oil and gas, petrochemical, power generation, and chemical processing.
