FBM100 P0973CA | Foxboro Industrial Pulse Input Interface

Product Description

Overview

The Foxboro FBM100 P0973CA is a high-speed pulse input Field Bus Module (FBM) designed for precise acquisition of frequency and pulse signals in industrial automation systems.
It converts pulses from field devices such as turbine meters, counters, and contact closures into reliable digital data for the Foxboro I/A Series DCS.
Moreover, the module provides channel-to-channel isolation, ensuring signal integrity even in electrically noisy environments.
Its compact design and rugged construction allow continuous operation in harsh conditions, making it ideal for chemical, oil & gas, power generation, and water treatment applications.
