Product Overview
The ABB Bailey NICS01 Control Terminal I/O Module is an industrial control and field I/O termination module used in ABB Bailey INFI 90 / Net 90 Distributed Control Systems (DCS). It is designed to provide a structured interface between control system I/O modules and field wiring, enabling reliable signal distribution for both analog and digital control signals.
The NICS01 functions as a control station and I/O termination interface, supporting communication between control processors, I/O slave modules, and field devices. It is widely used in legacy ABB Bailey architectures where stable signal routing, modular expansion, and structured cabinet wiring are required.
This module does not perform signal processing itself. Instead, it acts as a critical interface layer for control signal termination and distribution within the system.

Function and Working Principle
The ABB NICS01 operates as a central termination interface for control and I/O signals.
Working principle:
- Field devices (sensors, actuators, switches) generate control signals
- Signals are wired into the NICS01 termination points
- The module organizes and distributes signals to I/O slave modules
- Signals are routed to controllers and system processors via backplane
- Control logic processes signals in the DCS system
- Output commands are sent back through the same structure to field devices
This architecture ensures stable signal routing, reduced wiring complexity, and reliable system-level coordination.
