Product Overview
The ABB Bailey NSDM01 DC/DC Converter is an industrial power conversion module used in ABB Bailey INFI 90 / Net 90 Distributed Control Systems (DCS). It is designed to convert incoming DC voltage into regulated output voltages required by system electronics, ensuring stable power distribution across control modules.
This module is part of the system power architecture, typically used to supply clean and stable DC power to processors, I/O modules, and communication interfaces in distributed control cabinets.
The NSDM01 is widely used in legacy ABB Bailey automation systems deployed in power plants, petrochemical facilities, and large industrial process environments.

Function Description
The NSDM01 is used to convert and regulate DC power within the DCS system.
Its main functions include:
- Converting incoming DC voltage to required system levels
- Providing stable power to control system modules
- Filtering electrical noise and voltage fluctuations
- Supporting system-wide power distribution stability
- Ensuring continuous operation of sensitive electronics
It does not perform any control or communication functions; it is strictly a power conditioning module.
Working Principle
The module operates as a DC power regulation unit:
- Input DC power is supplied from the system power source
- The converter adjusts voltage levels using internal regulation circuits
- Output power is stabilized into required voltage rails
- Clean DC power is distributed to system modules
- Protection circuits manage overload and transient conditions
This ensures that all connected modules receive stable and noise-free power.
