Yokogawa NFDR541-P00 Relay Output Module – Product Description

Overview

The Yokogawa NFDR541-P00 is a high-reliability relay output module designed for CENTUM CS/VP distributed control systems. It converts digital control signals from the DCS into discrete ON/OFF relay outputs to drive field devices. Moreover, its compact, rack-mounted design with 16 relay channels and strong isolation ensures safe, robust operation in demanding industrial environments. Therefore, it is widely applied in oil & gas, petrochemical, power generation, and water treatment plants requiring precise relay actuation.
