Product Overview
The ABB Bailey NTMU02 INFI 90 Termination Mounting Unit is a mounting and interface component used in ABB Bailey INFI 90 control systems. It provides the physical mounting arrangement for termination hardware and helps organize the connection between INFI 90 system wiring and associated control modules.
Unlike an INFI 90 controller or I/O module, the NTMU02 does not execute control logic or process field signals. Its function is centered on the physical installation and interconnection of termination hardware within the control cabinet.
For replacement work, the NTMU02 should be matched with the existing INFI 90 termination arrangement. The installed termination units, cable assemblies, mounting points, and cabinet wiring should be checked before installation.

Product Features
- Termination mounting unit for ABB Bailey INFI 90 systems.
- Provides a structured mounting location for associated termination hardware.
- Supports organized cabinet-level installation of INFI 90 interface components.
- Helps maintain a defined physical arrangement for system wiring and connections.
- Suitable for control cabinet integration and system retrofit work.
- Functions as supporting hardware rather than an independent processor or I/O module.
- Useful for maintenance and replacement of existing INFI 90 termination assemblies.
Working Principle
The NTMU02 functions at the mechanical and hardware-interface level of an INFI 90 installation. Associated termination units and their connections are mounted and organized through the mounting arrangement, allowing cables and system wiring to be routed between termination hardware and the corresponding INFI 90 control equipment.
A simplified hardware arrangement is:
INFI 90 Control Hardware → Termination Interface → NTMU02 → Cabinet Wiring / Associated Termination Hardware
The NTMU02 itself does not perform signal processing or execute control logic. Its purpose is to support the physical organization of the termination hardware so that system connections can be installed and maintained in a consistent manner.
During maintenance, checking the mounting arrangement is important because loose hardware, damaged connection points, or incorrectly installed termination components can create intermittent wiring problems that may otherwise appear to be faults in the control electronics.
Role in an INFI 90 Control Architecture
| System Element | Function |
|---|---|
| INFI 90 Controllers | Execute configured process control logic |
| INFI 90 I/O Modules | Interface field process signals |
| Termination Units | Provide field and system wiring interfaces |
| ABB Bailey NTMU02 | Provides mounting support for termination hardware |
| Cable Assemblies | Connect termination hardware with control-system components |
| Control Cabinet | Provides the physical installation environment |
| Field Devices | Provide process measurements and receive control commands |
| Operator Interface | Provides process monitoring and operator control |
The NTMU02 belongs to the physical infrastructure layer of the INFI 90 architecture. It supports the installation of termination hardware but does not participate directly in controller logic execution or process signal computation.
Industrial Applications
| Application | Typical Use |
|---|---|
| Process Control | Mounting and organization of INFI 90 termination hardware |
| Power Generation | Control cabinet termination infrastructure |
| Chemical Processing | Structured installation of control-system interfaces |
| Oil and Gas | INFI 90 cabinet hardware integration |
| Industrial Utilities | Termination hardware mounting and organization |
| System Retrofit | Replacement of existing mounting infrastructure |
| Control Cabinet Maintenance | Mechanical support for termination assemblies |
Installation and Maintenance
- Confirm the complete NTMU02 part number before removing the existing mounting unit.
- Place the associated INFI 90 system in the appropriate maintenance state.
- Isolate relevant electrical circuits before working inside the control cabinet.
- Document the existing termination hardware arrangement before disassembly.
- Inspect mounting points, brackets, fasteners, and adjacent hardware for damage.
- Verify that the replacement unit matches the existing INFI 90 cabinet configuration.
- Install the NTMU02 in the designated mounting position.
- Secure the mounting hardware to prevent movement or vibration during operation.
- Install the associated termination units according to the original system arrangement.
- Check cable routing to ensure that wiring is not subjected to excessive mechanical stress.
- Verify all associated connectors and termination points before restoring system power.
- Confirm normal INFI 90 operation and check for wiring or hardware-related diagnostics after installation.

Technical FAQs
What is the primary function of the ABB Bailey NTMU02?
The NTMU02 is an INFI 90 Termination Mounting Unit. Its primary function is to provide physical mounting and organization for associated termination hardware within an INFI 90 control-system installation.
Does the NTMU02 process field signals?
No. The NTMU02 is mounting and support hardware. Signal processing, control logic, and field I/O functions are handled by the associated INFI 90 controllers, I/O modules, and termination interfaces.
Which components should be checked when replacing an NTMU02?
The associated termination units, mounting hardware, cable assemblies, cabinet mounting points, and existing wiring arrangement should be checked. The replacement should match the installed INFI 90 hardware configuration.
Can a loose mounting arrangement cause control-system problems?
Yes. Although the NTMU02 does not process signals, poor mechanical installation can place stress on connected cables, connectors, and termination hardware. Loose mounting or improperly routed wiring can therefore contribute to intermittent connection problems and should be corrected during maintenance.
