ABB Bailey NTSM01 Server Module Termination Unit

The ABB Bailey NTSM01 Server Module Termination Unit is a key component of the Bailey INFI 90 Distributed Control System (DCS). It serves as the termination interface between the NIS (Network Interface Server) or NPM (Network Processing Module) and various field devices or other controllers. The NTSM01 provides organized, reliable signal termination for the data and communication lines that connect to processor modules, ensuring accurate and stable signal routing throughout the control architecture.

Designed for critical control environments, the NTSM01 ensures electrical signal integrity, simplifies system wiring, and improves maintenance access. It is engineered with robust industrial standards, making it suitable for long-term deployment in power generation, chemical processing, oil & gas, water treatment, and other complex industrial infrastructures that use the ABB Bailey legacy DCS platform.
