Description
Product Overview
The ABB INIIT03 is a specialized interface terminal module designed for InfiNet industrial networks, forming a critical component of ABB’s Symphony Plus automation platform. Engineered to facilitate secure data transmission between field devices and control systems, this module serves as a physical connection point for InfiNet cables, enabling reliable communication in harsh industrial environments.
As a ruggedized terminal solution, the INIIT03 supports up to 32 nodes on a single InfiNet segment, ensuring seamless integration with controllers, I/O modules, and human-machine interfaces (HMIs). It features dual redundant ports for looped network configurations, enhancing system availability by eliminating single points of failure. The module operates on 24 V DC power and incorporates surge protection to withstand electrical disturbances, making it suitable for demanding applications in power generation, oil & gas, and process manufacturing.
The ABB INIIT03 simplifies network installation with its plug-and-play design, reducing commissioning time. Its compact form factor (102 x 160 x 40 mm) allows easy mounting in standard control panels, while the galvanically isolated architecture prevents ground loops and ensures signal integrity. By providing a robust physical layer for InfiNet networks, this module supports long-term system reliability and minimizes maintenance requirements.

Main Features and Advantages
Redundant Network Architecture: The INIIT03 features dual InfiNet ports for looped network topologies, automatically switching to the backup path in case of cable failure. This redundancy ensures <10 ms failover time, critical for uninterrupted operation in process control systems.
Rugged Industrial Design: Built to withstand vibrations (up to 50 G) and electromagnetic interference, the module meets IEC 61800-3 standards for industrial drives. Its wide temperature range (-20°C to +60°C) makes it suitable for outdoor installations and extreme climates.
Easy Installation and Maintenance: The module’s snap-in mounting bracket and tool-less terminal connections reduce installation time by 50%. Hot-swappable functionality allows replacement without powering down the network, minimizing downtime during maintenance.
Signal Integrity Assurance: Galvanic isolation (2500 Vrms) and surge protection (10 kV) prevent voltage spikes from damaging connected devices. Built-in diagnostics monitor network health, with LED indicators for power, communication status, and fault conditions.
Scalable Network Infrastructure: Supporting up to 32 nodes per segment, the INIIT03 enables seamless expansion of InfiNet networks. It is compatible with ABB’s full range of InfiNet-compatible modules, allowing flexible system design for small to large-scale applications.
Application Areas
Power Generation Plants: The ABB INIIT03 is used in thermal, hydro, and nuclear power stations to connect distributed control systems (DCS) with field devices like turbine sensors and generator switches. Its redundancy features ensure continuous monitoring of critical parameters during power production.
Oil and Gas Facilities: In upstream and downstream operations, the module withstands harsh offshore conditions, enabling reliable communication between subsea sensors and onshore control rooms. It supports real-time data transmission for pipeline pressure monitoring and wellhead control.
Chemical and Pharmaceutical Processing: The module facilitates secure data exchange in cleanroom environments, connecting batch controllers with mixers, valves, and analyzers. Its corrosion-resistant housing meets FDA and cGMP standards for pharmaceutical applications.
Water and Wastewater Treatment: Deployed in pumping stations and treatment plants, the INIIT03 monitors flow meters, level sensors, and chemical dosing systems. Its long network reach (1.2 km) allows integration of remote field devices in large-scale water management systems.
Manufacturing Automation: In automotive and food & beverage production lines, the module coordinates conveyor systems, robotic arms, and quality inspection equipment. Its low latency (≤1 ms) ensures precise timing for high-speed manufacturing processes.
