Product Introduction
The ABB Bailey NAOM01 is a robust and highly reliable analog output module designed for use in distributed control systems (DCS) such as ABB’s INFI 90 and Symphony series. Engineered to ensure accurate analog signal transmission, the NAOM01 provides analog outputs to control actuators, valves, drives, or other field devices in industrial automation processes.
This module translates digital control signals from the controller into analog current or voltage outputs, typically in the 4–20 mA or 0–10 VDC range, depending on system configuration. Its ability to function effectively in mission-critical industrial environments makes it a key component in process industries such as oil and gas, chemical production, power generation, and water treatment.
Known for its stability, precision, and durability, the NAOM01 helps improve process responsiveness and enhances the overall performance of control systems by ensuring seamless interaction with field devices.
