Product Introduction
The ABB Bailey IMRIO02 Remote I/O Module is a robust and highly dependable interface component designed for ABB’s INFI 90 Distributed Control System (DCS). It serves as a communication bridge between remote I/O racks and the main system controller, enabling accurate and real-time data exchange across distributed processing units.
In large-scale industrial operations, control systems often span wide physical areas. The IMRIO02 module allows field devices and sensors to be installed remotely from the central controller without sacrificing response time, signal integrity, or system redundancy. This makes it ideal for applications where scalability and operational reliability are crucial.
The IMRIO02 not only facilitates communication but also provides diagnostic capabilities, ensuring that field-level devices remain integrated with plant operations under all conditions. Its rugged construction, high-speed data processing, and seamless compatibility with Bailey INFI 90 architecture make it an essential component in mission-critical environments.
