The ABB Bailey NDSM01 is a versatile Digital Slave Module designed for the INFI 90 / Net 90 distributed control system (DCS). It is used to expand and manage discrete signal communication between field devices and the central control system, supporting both monitoring and control functions in industrial automation environments.
As part of ABB Bailey’s digital I/O architecture, the NDSM01 enables efficient handling of multiple digital signals such as status indications, interlocks, alarms, and control commands. It is widely used in power generation plants, oil refineries, petrochemical complexes, and large-scale manufacturing systems, where reliable digital signal processing is essential for operational safety and system coordination.
