ABB Bailey IMRIO22 Remote I/O Module

The ABB Bailey IMRIO22 is a Remote Input/Output (I/O) Module engineered for the INFI 90 Distributed Control System (DCS). It acts as a communication bridge between field devices and the centralized controller, allowing the collection of process data and control commands over long distances. The IMRIO22 expands I/O capabilities in large industrial environments where centralized wiring is impractical or cost-prohibitive.

Designed for high-performance and reliability, this module plays a critical role in decentralized control architectures. It provides deterministic I/O communications and supports a wide range of analog and digital signal types. The module communicates with the controller via INFI-NET, ensuring seamless integration and fast data transmission with minimal latency.
