FOXBORO FCM2F2 RH914YZ Fieldbus Communication Module

Product Description

• The FOXBORO FCM2F2 RH914YZ is a fiber-optic Fieldbus Communication Module used in the Foxboro I/A Series Distributed Control System (DCS).

• It enables long-distance, high-integrity communication between remote I/O and central controllers using fiber optics, providing immunity to electromagnetic interference and lightning-induced surges.

• Designed for use with 200 Series baseplates, it supports both redundant and non-redundant configurations for mission-critical applications.

• The module is ideal for installations where electrical isolation and extended communication distances are essential.
