YOKOGAWA NFAI135-S00 S2 ANALOG INPUT MODULE PLC (WL22-1)

Description:

The Yokogawa NFAI135-S00 S2 Analog Input Module is used in industrial control systems to receive and process analog signals from field transmitters and convert them into digital data for PLC or DCS systems. Commonly installed in Yokogawa STARDOM and process control platforms within chemical plants, power generation, and automation systems requiring accurate signal acquisition. Maintenance teams, OEMs, and system integrators use this module for system expansion, replacement of I/O modules, and ensuring reliable analog data input.

Applications:

The Yokogawa NFAI135-S00 S2 is used in industrial automation systems to collect analog signals such as 4–20 mA current or 1–5 V voltage from sensors and transmitters. It is commonly deployed in process plants, manufacturing systems, and environmental monitoring setups where variables like pressure, temperature, and flow must be continuously monitored. The module integrates with field control stations and supports stable data acquisition for process optimization and control.
