Product Overview
The ABB Bailey NKMP03-1 INFI 90 MFP Redundancy Cable is a dedicated connection cable used in ABB Bailey INFI 90 distributed control systems for redundant Multi-Function Processor (MFP) configurations. It provides the required electrical connection between compatible MFP redundancy components, supporting synchronization and communication between redundant processor units.
In high-availability industrial control applications, redundant MFP configurations are used to improve system reliability by allowing a backup processor to maintain control capability when the primary processor encounters a fault or requires maintenance. The NKMP03-1 cable acts as a key connection element within this redundancy structure.
With a 1-foot cable length, this model is designed for short-distance connections inside control cabinets where MFP modules and related interface components are installed in close proximity. It is commonly used in ABB Bailey INFI 90 systems deployed in power generation, oil and gas, chemical processing, and other continuous process industries.

The cable should be installed according to the original system wiring configuration and the connected MFP hardware requirements.
Working Principle
The NKMP03-1 functions as a passive electrical connection component within an ABB Bailey INFI 90 redundant processor architecture.
A typical connection path can be represented as:
Primary MFP Module ↔ NKMP03-1 Redundancy Cable ↔ Redundant MFP Component
During operation, redundant MFP modules exchange status information and synchronization signals to maintain coordinated operation between the active and standby processors.
The cable itself does not perform signal processing or execute control logic. Its main purpose is to provide a stable transmission path for redundancy-related signals, allowing the processor modules to operate as a coordinated redundant control unit.
Role in ABB Bailey INFI 90 Redundancy Architecture
The NKMP03-1 is installed within the redundancy connection layer of the INFI 90 control system.
A typical architecture can be represented as:
MFP Controller → Redundancy Interface → NKMP03-1 Cable → Backup Processor → INFI 90 Network
| System Layer | Function |
|---|---|
| MFP Controller | Executes process control tasks |
| Redundancy Interface | Manages processor backup operation |
| NKMP03-1 Cable | Transfers redundancy signals |
| INFI 90 Network | Provides system communication |
| Operator / Engineering Station | Enables monitoring and configuration |
The cable supports the communication path required for maintaining redundant processor availability.
Industrial Applications
The ABB Bailey NKMP03-1 is used in industrial environments where uninterrupted process control is required.
| Application | Typical Use |
|---|---|
| Power Generation | Redundant DCS processor connections |
| Oil & Gas Facilities | High-availability process control |
| Chemical Plants | Continuous process automation |
| Petrochemical Systems | Critical control applications |
| Utility Facilities | Reliable automation infrastructure |
| Water Treatment Plants | Process control systems |
| Manufacturing Lines | Industrial DCS operation |
| Process Industries | INFI 90 maintenance and upgrades |
Installation and Maintenance
Proper installation of the redundancy cable helps maintain reliable processor communication.
Recommended maintenance checks include:
- Confirm the correct NKMP03-1 model before installation.
- Verify compatibility with the existing MFP redundancy configuration.
- Inspect cable connectors for damage.
- Confirm secure connection at both ends.
- Check cable insulation condition.
- Avoid excessive bending during installation.
- Verify processor redundancy status after replacement.
- Monitor system alarms related to communication faults.
- Record cable replacement information.
- Keep spare cables available for critical systems.
When redundancy communication faults occur, the cable should be inspected together with MFP modules, interface components, and system configuration.

Technical FAQs
How is the NKMP03-1 used within an INFI 90 redundant MFP configuration?
The NKMP03-1 provides the physical connection required between compatible MFP redundancy components, allowing redundant processors to exchange coordination and status signals.
What makes the 1-foot NKMP03-1 cable suitable for cabinet installations?
The short cable length reduces excess wiring inside control cabinets, helping maintain cleaner layouts and shorter connection paths between closely installed processor components.
Can an NKMP03-1 cable be identified by cable length alone during system maintenance?
No. Cable length is only one identification factor. Engineers should also confirm the exact Bailey model number, connected modules, connector type, and redundancy configuration.
What system conditions may indicate a problem with an MFP redundancy cable?
Redundancy communication alarms, processor synchronization failures, or unexpected backup processor status changes may require inspection of the redundancy cable and related interface hardware.
