Product Overview
The ABB Bailey NIDO01 Digital Output Module is an industrial field termination interface module used in ABB Bailey INFI 90 / Net 90 Distributed Control Systems (DCS). It provides a structured connection between digital output processing modules and field devices such as actuators, solenoids, relays, and control indicators.
This module is a passive termination unit, meaning it does not perform signal processing or control logic. Instead, it organizes and distributes digital output signals from the control system to field equipment, ensuring stable switching performance and reliable wiring architecture.
The NIDO01 is widely used in discrete control environments where high channel density and stable output signal routing are required.

Function and Working Principle
The ABB NIDO01 operates as a structured digital output termination interface.
Working principle:
- The DCS controller generates digital output commands
- Commands are sent to digital output modules
- Signals are routed into the NIDO01 termination module
- The module distributes outputs to field wiring channels
- Field devices such as valves, relays, and actuators receive signals
- Devices execute ON/OFF control actions based on system logic
This ensures stable switching behavior, reduced wiring complexity, and reliable field execution.
