Product Overview
The ABB Bailey NIMP02 Multifunctional Processor Termination Module is an industrial processor-level termination and communication interface module used in ABB Bailey INFI 90 / Net 90 Distributed Control Systems (DCS). It is designed to support communication between multifunction processor modules and system-level components such as controllers, operator stations, and serial communication networks.
The NIMP02 works in combination with the NIMP01 module and is commonly used in redundant or multi-processor architectures, providing stable signal termination and communication routing for processor integration within the control system.
This module does not perform control processing. Instead, it acts as a dedicated interface layer ensuring reliable processor communication and system synchronization.

Function and Working Principle
The ABB NIMP02 operates as a redundant processor communication termination interface.
Working principle:
- Multifunction processor modules generate control and system data
- The NIMP02 provides termination for redundant or paired processor communication paths
- Communication signals are routed through RS-232-C or RS-485 serial links
- Data is exchanged between processors, system controllers, and operator stations
- The system maintains synchronization and redundancy integrity across processors
This architecture ensures high reliability, redundancy support, and stable processor-level communication in industrial control systems.
