Product Overview
The ABB Bailey NFCS01 Frequency Counter Module is a specialized signal acquisition component used within ABB Bailey Distributed Control Systems (DCS) — such as INFI 90, Network 90, and Symphony platforms. Its primary function is to measure and convert high‑speed digital pulse or frequency signals from field devices into processed data that can be used by central controllers for monitoring, control logic, and diagnostic purposes. This module is suitable for applications where precise frequency or event counting is essential, such as flow metering, turbine speed measurement, or high‑speed discrete input monitoring.
