Description
Product Overview
The NTMP01 is a Multi-Function Processor Termination Unit developed for ABB INFI 90 OPEN and Symphony Harmony distributed control architectures. It acts as the interface layer between Multi-Function Processor (MFP) modules and external field wiring, ensuring stable signal distribution, communication routing, and power interfacing within the control cabinet.
The unit is designed for cabinet-based installation and supports system-level integration of processor modules with field devices in complex process control environments.
Functional Role
This termination unit provides the physical and electrical connection point for MFP-based systems. It supports:
-
Digital and analog signal termination
-
Communication channel routing
-
Power distribution to connected processor modules
It ensures structured wiring organization and reduces direct field wiring complexity between control hardware and process instrumentation.

Electrical and Communication Design
The NTMP01 supports mixed serial communication architectures, enabling flexible integration with both RS-232-C and RS-485 based control networks. It provides centralized routing for control station communication links while maintaining electrical separation between field wiring and processor logic.
Signal integrity is maintained through controlled impedance routing and system-defined grounding practices.
Environmental and Installation Considerations
The unit is designed for installation within ABB-certified control cabinets. No additional cooling is required when operated within specified environmental limits.
To minimize electromagnetic interference effects, installation guidelines recommend:
-
Maintaining minimum separation from communication equipment
-
Keeping cabinet doors closed during operation
-
Following ABB wiring and grounding standards
System Integration
The NTMP01 operates as a passive system interface component within ABB distributed control architectures. It does not perform logic processing but ensures structured connectivity between MFP modules and field systems.
It is typically installed alongside processor and communication modules in modular control racks.
Typical Applications
-
Distributed process control system interfacing
-
Power plant control cabinet integration
-
Chemical processing control architectures
-
Industrial automation signal routing systems
-
Multi-module ABB Symphony Harmony installations
