The ABB Bailey NASI02 is an industrial-grade Analog Slave Input Module designed for the INFI 90 / Net 90 distributed control system (DCS). It is responsible for acquiring and transmitting analog process signals from field instruments to the central control architecture for monitoring, analysis, and process regulation.
Engineered for high-reliability automation environments, the NASI02 delivers stable analog signal handling with excellent noise immunity and long-term operational accuracy. It is commonly used in power generation plants, oil & gas facilities, petrochemical processing units, and continuous manufacturing industries, where precise analog data acquisition is critical for maintaining safe and efficient process control.
