Yokogawa NFCP050 CPU Module

Product Introduction

The Yokogawa NFCP050 is a high-performance CPU module developed for use within the ProSafe-RS Safety Instrumented System (SIS). As the core processing unit of the Safety Control Station (SCS), the NFCP050 is responsible for executing safety logic, handling communication with I/O modules, and managing diagnostics and redundancy functions for mission-critical industrial safety applications.

With its SIL3-certified architecture, robust design, and high processing speed, the NFCP050 ensures rapid, deterministic, and fault-tolerant performance even in hazardous operating environments. It enables end users to design and implement complex safety functions that comply with IEC 61508 and other global safety regulations.

Its compact form factor, low power consumption, and seamless integration with Yokogawa engineering tools (like SENG and SCS Configurator) make the NFCP050 an ideal choice for facilities seeking reliable and scalable safety system solutions.

Technical Specifications

Applications

The NFCP050 CPU module is used in Safety Instrumented Systems to provide fast and secure execution of safety functions across a variety of high-risk industries:
