Product Overview

The INIIT03 is a specialized network bridge component designed for the ABB Bailey Infi 90 Distributed Control System (DCS). Serving as a high-speed Infi-Net to Infi-Net Transfer Module, this hardware facilitates the transparent exchange of process data, control signals, and system variables between discrete Infi-Net communication rings. The INIIT03 is essential for expanding the geographical and logical boundaries of a control network, allowing multiple process areas to function as a singular, unified automation environment. By managing the complex routing and timing requirements of cross-ring data traffic, it ensures that critical information reaches its destination with deterministic consistency.

Network Architecture and Interface Capabilities

The INIIT03 is engineered for high-availability backbone communication within the Harmony Rack (HR) series, prioritizing data integrity and fault-tolerant connectivity.

• Module Type: High-speed network bridge / Transfer Interface.

• Data Throughput: Optimized for real-time, low-latency cross-ring transmission.

• Redundancy Support: Integrated logic for secondary network path failover to prevent communication loss.

• Physical Profile: 3.5cm x 31.5cm x 17.6cm.

• Mass: 0.54 kg.

• Thermal Management: Passive heat dissipation optimized for high-density DCS rack mounting.

• Origin: Precision manufactured in Sweden.

Strategic Process Deployments

The INIIT03 Transfer Module is a vital asset for large-scale industrial facilities that require synchronized control across expansive plant sites. In the energy management sector, it is frequently used to link the boiler control network with the turbine management ring, ensuring that load changes are coordinated across different segments of the power plant. Within the petrochemical and refining industries, the INIIT03 provides the necessary bandwidth to integrate remote I/O stations with the central control room without overwhelming a single network ring. Furthermore, its modular design within the Harmony Rack family allows for easy system scaling, enabling facility engineers to add new processing units or nodes to the Infi 90 architecture while maintaining high-speed communication and reducing the overall risk of system-wide downtime.
