Yokogawa NFDR541-P00 Relay Output Module – Product Description

Overview

The Yokogawa NFDR541-P00 is a high-performance relay output module designed for CENTUM CS/VP distributed control systems. It converts digital control signals into discrete ON/OFF relay outputs for field devices, including pumps, motors, and alarms. Moreover, the rack-mounted module features 16 relay channels with robust channel-to-channel and channel-to-system isolation, ensuring safe, reliable operation in demanding industrial environments. Therefore, it is ideal for oil & gas, petrochemical, power generation, and water treatment facilities.
