ABB Bailey INIIT01: Infi-Net to Infi-Net Transfer Module for Network Expansion

The INIIT01 from ABB Bailey functions as a dedicated Infi-Net to Infi-Net transfer module. It connects multiple Infi 90 network segments for expanded system capacity and coverage. This module facilitates data exchange between geographically distributed control nodes. Industrial facilities depend on its bridging capabilities for large-scale automation architectures.

Technical Specifications & Hardware Details

Network Bridging and Segment Isolation

The INIIT01 provides a transparent bridge between two Infi-Net network segments. Its dual processors manage bidirectional message flow without protocol conversion. You can install this module to extend network length beyond single-segment limitations. Furthermore, the design includes isolation that electrically separates each network segment. This isolation prevents fault propagation between connected network sections.

Physical Construction and Connectivity Layout

This transfer module features a rugged single-board design for standard Infi 90 card cages. Its edge connector seats securely into the system backplane. The INIIT01 includes dual coaxial connectors for network cabling on both segments. You can install or replace this module without disrupting network communications. The board layout separates the two network interfaces for signal integrity.

System Integration and Network Expansion

The module interfaces directly with the Infi-Net backbone for transparent data routing. It forwards messages between segments while maintaining network timing and addressing. The INIIT01 works alongside other Infi 90 components for complete system architecture. For similar industrial applications, static trip units and protective relays use comparable network bridging principles. However, this transfer module specifically addresses network expansion requirements within the Bailey ecosystem. Facilities rely on it for connecting distributed control areas across large facilities.
