Yokogawa NFLP121-S00 PROFIBUS-DP Communication Module

Product Introduction

The Yokogawa NFLP121-S00 PROFIBUS-DP Communication Module is a dedicated industrial communication interface that enables Yokogawa control systems to establish seamless data exchange with PROFIBUS-DP field devices. Designed to support complex plant architectures, the module ensures robust, standardized, and deterministic communication between control systems and distributed equipment.

At its core, the NFLP121-S00 is engineered around the EIA-RS485 standard, which is one of the most widely adopted physical layers for fieldbus communication. This makes the module highly versatile and compatible with numerous PROFIBUS-DP certified devices such as sensors, actuators, transmitters, and drives.

Unlike general-purpose communication modules, the NFLP121-S00 incorporates advanced isolation between the signal side and the system side, which safeguards the control architecture against electrical noise, ground potential differences, and transient disturbances. Its compact form factor, low power consumption, and Yokogawa-grade reliability make it particularly well suited for mission-critical industrial applications.

This module is not only a physical interface but also a key enabler of interoperability in automation systems. It translates control instructions into PROFIBUS-DP commands and ensures accurate, real-time feedback from field devices, thereby contributing to plant-wide efficiency, reliability, and safety.
