Product Overview
The ABB Bailey NTMF01 INFI 90 Multi-Function Controller Termination Unit is a termination and interface component used with ABB Bailey INFI 90 control systems. It provides the field-side connection point for controller-related signals and helps organize the electrical interface between external wiring and the associated control hardware.
In an INFI 90 installation, termination units are used to simplify cabinet wiring and establish defined connection points between field circuits and system modules. The NTMF01 is therefore a hardware interface component rather than a standalone controller or I/O processor.
For replacement work, the complete NTMF01 part number should be matched with the existing INFI 90 configuration. The connected controller, cable assemblies, terminal assignments, and field wiring should be checked before installation.

Product Features
- Multi-function controller termination unit for ABB Bailey INFI 90 systems.
- Provides an organized termination point for controller-related field wiring.
- Supports the electrical interface between external circuits and associated INFI 90 control hardware.
- Suitable for control cabinet wiring and system-level interconnection.
- Helps simplify maintenance by providing a defined termination interface.
- Intended to work as part of the INFI 90 hardware architecture rather than as an independent processor.
- Suitable for replacement and retrofit applications involving existing INFI 90 installations.
Working Principle
The NTMF01 operates at the termination and interconnection level of an INFI 90 control system. External field wiring is brought to the termination unit, where the corresponding circuits are connected to the associated controller or control-system hardware through the appropriate interface arrangement.
A simplified signal path is:
Field Wiring → NTMF01 → INFI 90 Controller / Control Hardware → Control Logic
The termination unit itself does not execute the controller’s application logic. Its function is to establish the required physical electrical connections and provide an organized interface between cabinet wiring and the controller-side hardware.
During troubleshooting, the termination unit is one point in the overall signal path. Checking terminal connections, cable continuity, connector condition, and the associated controller or I/O hardware can help determine whether a signal problem originates in the wiring interface or elsewhere in the control system.
Role in an INFI 90 Control Architecture
| System Element | Function |
|---|---|
| Field Instruments | Generate process measurements and discrete status signals |
| Field Wiring | Carries process and control signals to the cabinet |
| ABB Bailey NTMF01 | Provides controller-related signal termination and interconnection |
| INFI 90 Controller | Executes configured control functions and application logic |
| I/O Hardware | Interfaces process signals with the control system |
| INFI 90 Network | Transfers control and system data between distributed components |
| Operator Interface | Provides process monitoring, alarms, and operator control |
| Final Control Devices | Execute control commands in the process |
The NTMF01 sits between the field/cabinet wiring and the associated controller hardware. Its contribution is primarily physical signal termination and routing, allowing the controller and other INFI 90 components to operate with an organized field interface.
Industrial Applications
| Application | Typical Use |
|---|---|
| Process Control | Controller-related field signal termination |
| Power Generation | Control cabinet interconnection in INFI 90 installations |
| Chemical Processing | Organized field wiring and controller interfaces |
| Oil and Gas | Signal termination within process control cabinets |
| Industrial Utilities | Interface between field circuits and INFI 90 control hardware |
| System Retrofit | Replacement of existing INFI 90 termination hardware |
| Maintenance Spares | Stock replacement for installed Bailey control systems |
Installation and Maintenance
- Confirm the complete NTMF01 part number before removing the existing termination unit.
- Place the associated INFI 90 control system in the required maintenance state.
- Isolate applicable electrical circuits according to the site’s safety procedures.
- Document existing terminal assignments and cable connections before disassembly.
- Inspect terminal points and connectors for looseness, corrosion, contamination, or physical damage.
- Verify that the replacement unit matches the existing INFI 90 system configuration.
- Install the NTMF01 in the correct cabinet position and secure it properly.
- Reconnect field and controller-side wiring according to the approved wiring documentation.
- Check cable routing and strain relief to prevent unnecessary stress on terminals and connectors.
- Verify terminal continuity and connection integrity before restoring system power.
- Check associated controller and I/O diagnostics after the system is energized.
- Test representative signals and controller functions before returning the control system to normal operation.

Technical FAQs
What is the function of the ABB Bailey NTMF01?
The NTMF01 is an INFI 90 Multi-Function Controller Termination Unit. It provides a defined termination and interconnection point between controller-related wiring and the associated INFI 90 control hardware.
Does the NTMF01 perform controller logic?
No. The NTMF01 is a termination and interface component. Control logic and application processing are performed by the associated INFI 90 controller and other control-system hardware.
What should be verified before replacing an NTMF01?
The complete part number, existing INFI 90 architecture, controller connections, cable assemblies, terminal assignments, and field wiring should be verified. Recording the original wiring before removal is particularly useful when replacing an installed termination unit.
How can a wiring problem at the NTMF01 be isolated?
Start by checking terminal tightness and connector seating, then verify cable continuity and the corresponding field circuit. If the physical connections are correct, inspect the associated controller and I/O diagnostics to determine whether the fault is further upstream or downstream of the termination unit.
