Product Overview
The ABB Bailey NQRS02 Fast Response Subordinate Module is a high-speed slave/control I/O module used in ABB Bailey INFI 90 / Net 90 Distributed Control Systems (DCS). It is designed to support fast response control operations by acting as a subordinate module under higher-level controller or fast response processing units.
This module is commonly used in time-sensitive industrial control applications, where rapid signal handling, fast status updates, and low-latency response are required.
It belongs to the ABB Bailey “quick/fast response” module family, typically working alongside fast response controllers such as NQRC series modules.

Function Description
The NQRS02 is designed to support fast-response control execution at the subsystem level.
Its main functions include:
- Receiving high-speed control commands from master/fast response controllers
- Providing rapid status feedback to the control system
- Supporting low-latency signal exchange in real time
- Acting as a subordinate execution module in control loops
- Assisting in time-critical process coordination
It does not perform full control logic independently but operates as part of a distributed fast-response control structure.
Working Principle
The module operates in coordination with higher-level fast response controllers:
- Control commands are generated by a master controller (such as fast response controller modules)
- NQRS02 receives these commands via system backplane communication
- The module executes subordinate-level response actions
- Status and feedback signals are returned immediately to the controller
- This loop ensures rapid system reaction to process changes
This structure minimizes delay and improves control responsiveness in dynamic industrial processes.
System Role
Within ABB Bailey INFI 90 / Net 90 architectures, NQRS02 is used as:
- Fast response subordinate execution module
- High-speed I/O support unit
