ABB Bailey Infi 90 & Net 90

The Bailey INFI 90 and Net 90 are distributed control systems (DCS) developed by Bailey Controls, now part of ABB, designed to provide comprehensive process automation solutions across various industries.

Net 90: Introduced in the 1980s, Net 90 was among the early DCS platforms, offering advanced control strategies and algorithms for precise monitoring and control of industrial processes. It enabled operators to monitor real-time data, implement control strategies, and manage alarms and events effectively. 

INFI 90: Building upon the foundation of Net 90, INFI 90 was introduced in 1988, featuring a unique architecture and enhanced functionality. It seamlessly integrates various control and monitoring components into a unified platform, enabling comprehensive management and optimization of operations.
