Product Overview
The ABB Bailey NKMP11-2 INFI 90 MFP Redundancy Cable is a specialized connection cable used in ABB Bailey INFI 90 distributed control systems to support redundant Multi-Function Processor (MFP) configurations. It provides the electrical connection required between compatible MFP redundancy components, allowing processors and related interfaces to maintain coordinated operation.
In industrial process control systems, redundant MFP configurations are commonly implemented where continuous operation and high system availability are essential. The NKMP11-2 cable supports this architecture by providing a reliable signal pathway for redundancy-related communication between processor components.
Featuring a 2-foot cable length, the NKMP11-2 is suitable for short-range connections within automation cabinets and control racks. It is commonly installed in critical process industries such as power generation, oil and gas, chemical processing, and large-scale manufacturing facilities using ABB Bailey INFI 90 systems.

Working Principle
The NKMP11-2 works as a passive interconnection component in an ABB Bailey INFI 90 redundant processor system.
A typical connection path can be represented as:
Primary MFP Component ↔ NKMP11-2 Cable ↔ Redundant MFP Component
Within a redundant MFP architecture, processor modules exchange synchronization and status information to maintain coordination between the active and standby control paths.
The cable does not perform independent signal processing or control operations. Instead, it provides the physical transmission path required for redundancy communication, allowing connected processor components to operate as part of a unified control system.
Role in ABB Bailey INFI 90 Architecture
The NKMP11-2 is installed in the redundancy communication layer of ABB Bailey INFI 90 systems.
A typical system structure can be represented as:
MFP Processor → Redundancy Interface → NKMP11-2 Cable → Backup Processor → INFI 90 Network
| System Layer | Function |
|---|---|
| MFP Processor Modules | Execute control algorithms |
| Redundancy Interface | Manages backup processor coordination |
| NKMP11-2 Cable | Transfers redundancy signals |
| INFI 90 Communication Network | Provides system-wide data exchange |
| Engineering / Operator Station | System configuration and monitoring |
The cable helps maintain communication continuity between redundant processor elements.
Industrial Applications
The ABB Bailey NKMP11-2 is commonly used in industries requiring highly reliable process control systems.
| Application | Typical Use |
|---|---|
| Power Generation | Redundant DCS processor connection |
| Oil & Gas | Continuous process automation |
| Chemical Processing | High-availability control systems |
| Petrochemical Plants | Critical process monitoring |
| Utility Facilities | Reliable control infrastructure |
| Water Treatment | Distributed control applications |
| Manufacturing Systems | Automation system maintenance |
| Process Industries | INFI 90 system upgrades |
Installation and Maintenance
Proper cable installation is important for maintaining redundancy communication reliability.
Recommended maintenance checks include:
- Confirm the correct NKMP11-2 model before installation.
- Verify compatibility with existing MFP redundancy hardware.
- Inspect cable connectors and terminals.
- Ensure secure connection at both ends.
- Check cable insulation condition.
- Avoid mechanical stress during routing.
- Confirm processor redundancy status after installation.
- Monitor system alarms and communication status.
- Record replacement information.
- Maintain spare cables for critical control systems.
If redundancy communication errors occur, the cable should be inspected together with connected processor modules and interface components.

Technical FAQs
What redundancy function does the ABB Bailey NKMP11-2 cable support?
The NKMP11-2 provides the physical connection required for communication between compatible MFP redundancy components, supporting coordinated operation between redundant processors.
How should the NKMP11-2 be selected when replacing an existing INFI 90 cable?
Replacement selection should be based on the original cable model number, connected MFP hardware, redundancy configuration, connector requirements, and installed system architecture rather than cable length alone.
What type of system events may require inspection of an MFP redundancy cable?
Processor synchronization failures, redundancy status alarms, or unexpected controller switchover behavior may require checking the cable connection and associated interface components.
Why are short-length redundancy cables commonly used inside INFI 90 cabinets?
Short cables such as the NKMP11-2 help reduce unnecessary wiring inside control cabinets, improving installation organization while maintaining reliable communication between closely positioned modules.
