Yokogawa NFAF135-S50 Description

The Yokogawa NFAF135-S50 Frequency Input Module is designed for integration 

into the Centum VP Distributed Control System (DCS), enabling the measurement 

and processing of frequency-based signals in industrial applications. This module is 

ideal for environments where monitoring of high-speed devices, such as flow 

meters, tachometers, or speed sensors, is required.

Equipped with 8 input channels, the NFAF135-S50 allows for simultaneous frequency 

input processing, making it highly efficient in systems that monitor multiple parameters 

at once. It supports a broad input frequency range from 0 to 25 kHz, accommodating 

the needs of various industrial sensors. This module ensures high accuracy in 

capturing pulse-based signals, which are then transmitted to the control system for 

real-time analysis and decision-making.

In addition to its impressive frequency range, the NFAF135-S50 includes built-in 

signal conditioning features, such as filtering, which helps to eliminate noise and 

ensure reliable data transmission even in electrically noisy environments. Its 24 V 

DC power supply and compatibility with the Centum VP system make it a seamless 

fit within Yokogawa's DCS solutions, enabling smooth integration and enhancing 

system performance.

The module is designed to operate in extreme conditions, with an operating 

temperature range of -20°C to +60°C, making it suitable for a wide range of 

industrial environments, from power plants to manufacturing facilities. With its 

compact size and durable construction, the Yokogawa NFAF135-S50 Frequency 

Input Module provides reliable, real-time frequency data essential for process control 

and monitoring applications.
