ABB INIIT03 Symphony Harmony INFI-Net to INFI-Net Transfer Module
Product Overview
The ABB INIIT03 (often referenced as INIIT-03 3E-38) is a high-speed communication bridge designed for the Symphony Harmony and INFI 90 Distributed Control Systems (DCS). Its primary function is to facilitate seamless data transfer between two separate INFI-Net communication loops, allowing for the integration of multiple subsystems into a unified control network. The INIIT03 manages high-speed data exchange with robust optical and electrical isolation, ensuring that disturbances in one network do not propagate to another. This module is vital for large-scale industrial plants where complex, distributed architectures require reliable inter-network connectivity and redundancy to maintain maximum uptime.
