Description
Product Overview
The ABB INIIT03 is an advanced communication interface module from the Industrial IT (800xA) system family, designed to function as an Intelligent Interface to Turck’s fieldbus-independent, decentralized I/O system. This gateway module seamlessly bridges ABB’s high-level control environment with the versatile and robust Turck BL20/BL67 remote I/O stations. The ABB INIIT03 handles complex protocol conversion and data management, enabling the 800xA system to transparently access and control a wide array of digital and analog field devices connected to the remote Turck I/O blocks. This integration provides exceptional flexibility for distributed automation architectures, allowing for cost-effective and modular I/O deployment while maintaining the powerful engineering, visualization, and diagnostic capabilities of the ABB ecosystem.

Application Scenarios
Distributed Process Control: Deploying remote I/O clusters close to field devices in large plant areas like tank farms, packaging halls, or material yards in chemical, food & beverage, or logistics facilities.
Machine Integration: Connecting OEM machinery equipped with a Turck BL I/O interface directly into a plant-wide ABB 800xA DCS, simplifying integration and providing uniform diagnostics.
Modular Skid & Package Plant Control: Serving as the primary I/O interface for skid-mounted process units that are pre-equipped with Turck remote I/O, allowing for “plug-and-produce” connectivity to the central DCS.
