The ABB Bailey NASM01 is a reliable Analog Slave Module developed for the INFI 90 / Net 90 distributed control system (DCS). It is designed to support analog signal communication and distributed I/O processing between field instrumentation and the central control architecture.
As part of the ABB Bailey analog subsystem, the NASM01 enhances system scalability by expanding analog signal handling capacity while maintaining stable communication with master control modules. The module is widely deployed in power generation, petrochemical processing, oil & gas operations, and large-scale industrial automation systems, where accurate analog data transmission is essential for continuous process control.
