What Is an Intelligent Integrated Node (IIN)?

Built on the ioPAC 6500 Series industrial edge controller, the Intelligent Integrated Node (IIN) is a unified automation controller platform engineered for harsh, hazardous, and unmanned remote industrial sites.

From Fragmented Automation Architectures to a Single Integrated System

Many industrial automation projects rely on a patchwork of device brands, standalone gateways, and disconnected configuration tools, a setup that quickly drives up system management and maintenance complexity.

The ioPAC 6500 Series simplifies this architecture. Powered by the IINxpress integrated software suite, it consolidates I/O, communication, and control functions onto a single rugged edge controller, reducing infrastructure complexity and improving operational visibility across remote automation applications.
