Product Overview
The ABB Bailey NDLS02 Digital Logic Station is an operator interface and logic station module used in ABB INFI 90 / Network 90 distributed control systems (DCS). It is designed to provide manual digital interaction, logic control access, and operator-level interface functions for industrial process systems.
The NDLS02 is typically used in environments where operators require direct control, indication, and logic interaction with the control system without accessing deeper controller configuration layers.

Function and Working Principle
The NDLS02 acts as a human–machine logic interface within the ABB Bailey control system.
Its main functions include:
- Providing pushbutton-based manual control inputs
- Displaying system status using LED indicators
- Supporting operator interaction with control logic functions
- Allowing manual override or control in specific operating modes
- Displaying real-time system logic states
- Supporting maintenance and diagnostic operations
The module communicates with the DCS system to reflect process states and accept operator commands, making it an important interface between human operators and automated control logic.
Role in Industrial Control Systems
Within ABB INFI 90 architecture, NDLS02 functions as an operator logic and control interface station.
Typical roles include:
- Manual intervention in control logic sequences
- Status indication for system and process states
- Supporting start/stop and control selection functions
- Assisting maintenance and troubleshooting operations
- Providing local control capability in distributed environments
