ABB IMRI002 INFI 90 24VDC Redundant Communication Unit

Product Description

Redundant Communication and Interface Overview

The IMRI002 (Part Number: IMRI002) is a high-availability Redundant Interface Module engineered for the ABB Bailey INFI 90 Distributed Control System (DCS). Functioning as a Remote I/O Slave, the IMRI002 (Model: IMRI002) provides the essential communication bridge between localized I/O clusters and the primary INFI 90 Plant Loop network. This module is specifically designed to eliminate single points of failure by supporting dual communication paths, ensuring that process data and control commands remain uninterrupted even in the event of a cable fault or port failure. Its deterministic architecture makes it ideal for mission-critical applications where system uptime is non-negotiable.
