ABB Bailey AIN300 P-HB-AIN-30010 000 Harmony Block Module

The ABB Bailey AIN300 P-HB-AIN-30010 000 is a Harmony Block Analog Input (AI) Termination Module designed to provide a secure and organized interface between field analog instrumentation and the ABB Bailey INFI 90 Distributed Control System (DCS). As part of the Harmony Series I/O architecture, the AIN300 plays a critical role in ensuring accurate and noise-resistant transmission of analog signals such as temperature, pressure, and flow measurements.

Built to support analog input interface modules (e.g., IIA101, IIA102), the AIN300 allows for precise and reliable signal conditioning, thanks to its high-integrity screw terminals, field-shielded wiring compatibility, and robust construction. The module acts as a physical termination point where sensor wiring is grouped and channeled efficiently to the control system.

With widespread usage in industries such as power generation, chemical processing, and water treatment, the AIN300 delivers consistent performance, ensuring long-term system uptime and data accuracy across complex industrial automation environments.
