Product Overview
The ABB Bailey NKTK01 INFI 90 SOE Time Synchronization Cable is a time-synchronization cable used with ABB Bailey INFI 90 Sequence of Events (SOE) systems.
SOE applications require a common time reference so that events generated by different control-system points can be recorded and compared in chronological order. The NKTK01 provides the physical connection associated with the time-synchronization path.
The NKTK01 is specified with an optional cable length, allowing the cable configuration to suit the applicable INFI 90 installation. It is intended for system architectures where synchronized timing information must be transferred between the relevant synchronization and SOE equipment.
The cable itself does not perform event processing or time calculation. Its role is to maintain the physical signal connection required by the synchronization system.

Working Principle
The NKTK01 forms part of the physical timing path used by an INFI 90 SOE system.
A simplified arrangement is:
Time Reference → Synchronization Equipment → NKTK01 → SOE Hardware → Event Timestamping
The synchronization signal establishes a common time reference for participating system components.
When an event occurs, the SOE system associates the event with the synchronized time information. Multiple events can then be arranged according to their occurrence time.
This is important during equipment trips, process disturbances, protection actions, and alarm sequences where determining which event occurred first can be critical to troubleshooting.
Role in INFI 90 SOE Architecture
The NKTK01 belongs to the interconnection layer of the SOE system.
| System Element | Function |
|---|---|
| Time Reference | Establishes the system time |
| Synchronization Hardware | Distributes timing information |
| NKTK01 | Provides the synchronization cable connection |
| SOE Hardware | Records event information |
| Event Sources | Generate discrete system events |
| INFI 90 Control System | Provides control and monitoring functions |
| Operator Interface | Displays alarms and event records |
The cable supports the connection between synchronization equipment and the associated SOE hardware.
Time Synchronization and Event Recording
A synchronized SOE system can correlate events occurring at different locations.
| Event-Recording Function | Purpose |
|---|---|
| Timestamping | Records the time associated with an event |
| Sequence Recording | Establishes event order |
| Alarm Correlation | Relates multiple alarms to a common timeline |
| Trip Analysis | Helps identify the progression of a disturbance |
| Historical Review | Supports post-event investigation |
| System Diagnostics | Helps identify abnormal operating sequences |
For complex control systems, this information can be useful when several equipment states change within a very short interval.
Cable Configuration
The NKTK01 is specified with an optional cable length rather than a single fixed length.
This configuration can be relevant when the physical distance between synchronization equipment and the SOE system varies between installations.
| Configuration Item | Specification |
|---|---|
| Cable Family | NKTK01 |
| Length | Optional |
| Application | INFI 90 SOE synchronization |
| Function | Timing-signal interconnection |
The selected cable configuration should match the physical arrangement of the associated INFI 90 equipment.
Industrial Applications
| Application | Typical Use |
|---|---|
| Power Generation | Sequence of Events recording |
| Thermal Power Plants | Alarm and trip analysis |
| Turbine Systems | Synchronized event monitoring |
| Boiler Control | Process disturbance analysis |
| Process Automation | Time-correlated event recording |
| Industrial Utilities | SOE monitoring |
| Plant Control | Event sequence reconstruction |
| INFI 90 Maintenance | Synchronization cable replacement |
Installation and Maintenance
- Confirm the NKTK01 model.
- Determine the required cable length for the installation.
- Identify the synchronization source and receiving equipment.
- Record the existing cable routing and connection arrangement.
- Isolate the applicable equipment when required.
- Inspect connectors before installation.
- Check the cable for mechanical damage.
- Avoid excessive bending or mechanical stress during routing.
- Connect the cable to the designated synchronization interfaces.
- Confirm secure connector engagement.
- Restore the applicable system connections.
- Verify synchronization status.
- Check SOE timestamp behavior.
- Compare event times from multiple system points.
- Monitor the system for synchronization alarms.
When event timestamps appear inconsistent, check the complete synchronization path rather than the cable alone.

Technical FAQs
What distinguishes the NKTK01 from a fixed-length SOE synchronization cable?
The NKTK01 is specified with an optional cable length, whereas models such as NKST11-10, NKST11-20, and NKST11-30 identify specific cable lengths.
Does the NKTK01 generate the synchronization time?
No. The cable provides the physical connection for the synchronization path. The time reference and synchronization functions are handled by the associated INFI 90 equipment.
Why does cable length matter in an SOE system?
The cable must physically connect the relevant synchronization equipment without creating an unsuitable routing arrangement. The appropriate length also helps avoid unnecessary cable loops or excessive mechanical stress.
What should be checked if SOE timestamps become inconsistent?
Check the time-reference source, synchronization equipment, NKTK01 connections, receiving SOE hardware, and associated diagnostics. Comparing timestamps from multiple event sources can help identify where the synchronization path is being affected.
