ABB Bailey INFI 90: The Backbone of Industrial Control

ABB Bailey INFI 90: The Backbone of Industrial Control

Why Is ABB Bailey INFI 90 Still Relevant in Modern Industries?

The ABB Bailey INFI 90 Distributed Control System (DCS) has been a cornerstone in the world of industrial automation for decades. Although newer control technologies continue to emerge, the INFI 90 system remains highly relevant due to its proven reliability, modularity, and integration capabilities. Many industries—ranging from power generation to chemical processing—still rely on ABB Bailey INFI 90 because of its ability to handle complex process automation tasks with stability and precision.

What Makes ABB Bailey INFI 90 Unique in Industrial Applications?

Unlike conventional automation platforms, ABB Bailey INFI 90 is specifically designed for scalability and fault-tolerant operation. The system integrates controllers, human-machine interfaces (HMI), and I/O modules into a unified architecture that can be expanded as needed. It is especially well-suited for mission-critical processes, where uptime and accurate process control directly affect production efficiency and safety.

The Importance of ABB Bailey INFI 90 DCS in Industrial Automation

The ABB Bailey INFI 90 DCS plays a vital role in industrial automation by enabling centralized monitoring and decentralized control. Its distributed nature allows each module to operate semi-independently while still contributing to the overall process control system. This architecture ensures high system availability and reduces the risk of total system failure.

From power plants and refineries to paper mills and steel factories, ABB Bailey INFI 90 has provided a stable foundation for process control. The system supports advanced control strategies, real-time monitoring, and seamless integration with modern communication protocols. This makes it easier for industries to extend the lifecycle of their automation infrastructure without sacrificing performance.

One of the key modules in the INFI 90 system is the IMAS011, which demonstrates the flexibility and robustness of ABB’s engineering approach.

Technical Parameters of IMAS011

The IMAS011 module is essential in ABB Bailey INFI 90 environments, providing reliable performance within the DCS framework. Below is a summary of its parameters:

The IMAS011 ensures that analog signals from field instruments are reliably captured, conditioned, and transferred to the control system for processing. In fact, IMAS011 modules are known for their stability, making them a trusted choice in industries where precise analog measurements are critical.

ABB SPBRC410 SPBRC41000000 P-HC-BRC41000000 Industrial Controller

ABB SPBRC410 / BRC410 / P-HC-BRC41000000 is a Bridge Controller / Control Processor module, originally part of the ABB Bailey INFI 90 DCS family, later rebranded under Symphony Plus / Harmony Rack platforms.

ABB SPASI23 Analog Input Module

SPASI23 is an analog input module designed for ABB's DCS / control systems (including Symphony / INFI / Harmony platforms) to convert field analog signals into digital data for the controller. It is often backwards-compatible: SPASI23 may replace older modules (e.g. IMASI03/IMASI13) with minimal configuration adjustments.

ABB SPDSI22 Digital Input Module

The SPDSI22 is an ABB Digital Input (DI) module used to introduce digital field signals (such as switches, relay contact signals, dry contacts, or wet contacts) into a DCS/control system. It provides multi-channel status signal inputs to the controller for monitoring on/off status, alarms, interlocks, fault signals, and more.
