Product Overview
The ABB Bailey NKMP01-2 INFI 90 MFP Redundancy Cable is a dedicated system connection cable used in ABB Bailey INFI 90 distributed control systems for redundant Multi-Function Processor (MFP) configurations. It provides the physical connection required between redundant MFP-related components, supporting coordinated operation and communication between primary and backup control modules.
In INFI 90 architectures where high availability is required, redundant processor configurations help maintain continuous control operation during module failures or maintenance activities. The NKMP01-2 cable serves as part of this redundancy arrangement by providing a stable connection path between compatible system components.
With a 2-foot cable length, the NKMP01-2 is suitable for compact cabinet installations where MFP modules or related interface components are installed in close proximity. It is commonly used in industrial applications including power plants, chemical facilities, oil and gas installations, and other process automation environments.

Working Principle
The NKMP01-2 operates as a passive connection component within an ABB Bailey INFI 90 redundant control architecture.
A typical connection path can be represented as:
Primary MFP Module ↔ NKMP01-2 Cable ↔ Redundant MFP Interface / Backup Processor
In a redundant MFP configuration, control system components exchange status information and synchronization signals to maintain coordinated operation between active and standby processors.
The NKMP01-2 does not execute control logic or process data independently. Its function is to provide a stable electrical connection that allows compatible MFP components to exchange required redundancy-related signals.
Role in ABB Bailey INFI 90 Redundancy Architecture
The NKMP01-2 is installed within the redundancy connection layer of an INFI 90 control system.
A typical architecture can be represented as:
Controller Layer → MFP Modules → NKMP01-2 Redundancy Cable → Backup Processing Layer → INFI 90 Control Network
| System Layer | Function |
|---|---|
| MFP Controller Modules | Execute control operations |
| Redundant Processor Configuration | Provides backup control capability |
| NKMP01-2 Cable | Transfers redundancy-related signals |
| INFI 90 Network | Supports system communication |
| Engineering / Operator System | Enables monitoring and configuration |
The cable helps maintain the communication path required for redundant processor operation.
Industrial Applications
The ABB Bailey NKMP01-2 is mainly used in industries where continuous process control operation is required.
| Application | Typical Use |
|---|---|
| Power Generation | High-availability DCS control |
| Oil & Gas Facilities | Redundant process control |
| Chemical Plants | Critical automation systems |
| Petrochemical Industry | Continuous production control |
| Utility Systems | Reliable control infrastructure |
| Water Treatment Plants | Process monitoring systems |
| Manufacturing Facilities | Industrial automation control |
| Process Industries | INFI 90 system maintenance |
Installation and Maintenance
Proper installation is important for maintaining redundancy communication performance.
Recommended maintenance checks include:
- Confirm the correct NKMP01-2 cable model.
- Verify compatibility with installed MFP modules.
- Check connector condition before installation.
- Ensure both ends are securely connected.
- Inspect cable insulation and physical condition.
- Avoid excessive bending or mechanical stress.
- Verify redundancy status after installation.
- Check processor synchronization information.
- Record cable replacement details.
- Maintain spare cables for critical systems.
When redundancy faults occur, the cable should be inspected together with MFP modules, interface components, and system configuration parameters.
