ABB Bailey IMRAI12 Non-Isolated Input Module

Product Introduction

The ABB Bailey IMRAI12 is a high-performance non-isolated analog input module engineered to meet the rigorous demands of industrial automation and control systems. As part of ABB’s renowned Infi 90 series, the IMRAI12 is designed for accurate signal processing in environments where isolation is not a critical requirement. It is commonly used in process control systems to monitor and interface analog inputs such as temperature sensors, pressure transducers, and other signal-generating devices.

The IMRAI12 integrates seamlessly with ABB Bailey’s DCS (Distributed Control System) architecture, offering robust compatibility and reliable long-term performance. With its 12-channel input design, it enables high-density signal acquisition while maintaining system integrity and low latency.

Product Specifications

Applications

The ABB IMRAI12 module is widely used in industrial environments requiring reliable, non-isolated signal acquisition. Key application areas include:

• Petrochemical Plants – for analog sensor readings like temperature, pressure, and flow rate.

• Power Generation – for interfacing analog data to control loops in thermal and hydroelectric plants.

• Manufacturing Automation – integrated into SCADA and DCS systems for monitoring machine conditions.

• Water Treatment Facilities – monitoring water quality parameters such as pH, turbidity, and conductivity.

• Pharmaceuticals & Food Processing – tracking analog process conditions where real-time monitoring is crucial.

Product Advantages

• High Channel Density: Supports 12 analog inputs in a compact module, reducing space requirements.

• Reliable Signal Processing: Equipped with high-precision A/D converters ensuring accurate data capture.

• Seamless Integration: Designed to work directly with ABB Bailey’s Infi 90 systems.

• Cost-Effective: Non-isolated design is economical in applications where electrical isolation is unnecessary.

• Durable Build: Robust industrial-grade construction suitable for demanding environments.

• Long Product Lifecycle: ABB’s support and backward compatibility with legacy systems ensure longevity.
