Product Overview
The ABB Bailey NKTK01-15 INFI 90 SOE Time Synchronization Cable is a dedicated cable for time synchronization in ABB Bailey INFI 90 Sequence of Events (SOE) applications.
SOE systems use a common time reference to associate events with accurate timestamps and establish the chronological relationship between multiple alarms, trips, status changes, and process events. The NKTK01-15 provides the physical connection for the applicable synchronization path.
The NKTK01-15 is the 15-foot version of the NKTK01 cable family. It is suited to INFI 90 installations where the synchronization interfaces require a 15-foot connection.
The cable functions as a passive interconnection component and does not independently generate timestamps or process SOE events.

Working Principle
The NKTK01-15 transfers the applicable synchronization signal between designated interfaces in an INFI 90 SOE system.
A simplified signal path is:
Time Reference → Synchronization Interface → NKTK01-15 → SOE Hardware → Event Timestamping
The synchronization equipment supplies the time reference, while the cable maintains the physical connection to the receiving SOE hardware.
Once synchronized, the SOE system can associate detected events with the common time reference. This allows events generated by different system points to be arranged chronologically.
Accurate event ordering is particularly useful during equipment trips, process disturbances, and sequences involving multiple alarms or status changes.
Role in INFI 90 SOE Architecture
The NKTK01-15 belongs to the physical interconnection layer of the SOE timing architecture.
| System Element | Function |
|---|---|
| Time Reference | Establishes system time |
| Synchronization Interface | Distributes timing information |
| NKTK01-15 | Carries the synchronization connection |
| SOE Hardware | Records event information |
| Event Sources | Generate system events |
| INFI 90 Control System | Provides control and monitoring |
| Operator Interface | Displays alarms and event records |
15-Foot Cable Configuration
The NKTK01-15 identifies the 15-foot configuration within the NKTK01 family.
| Model | Cable Length |
|---|---|
| NKTK01 | Optional |
| NKTK01-10 | 10 feet |
| NKTK01-15 | 15 feet |
| NKTK01-20 | 20 feet |
| NKTK01-30 | 30 feet |
The fixed 15-foot configuration can be used where the physical separation between the relevant synchronization interfaces matches this connection requirement.
SOE Event Correlation
Synchronized timing allows control-system events to be analyzed against a common chronological reference.
| Event Information | Purpose |
|---|---|
| Event Timestamp | Identifies when an event occurred |
| Event Sequence | Establishes the order of events |
| Alarm Record | Tracks abnormal conditions |
| Trip Record | Supports equipment-trip investigation |
| Status Change | Shows equipment-state transitions |
| Historical Data | Supports post-event analysis |
This information can help engineers reconstruct the progression of a plant disturbance and identify the relationship between multiple events.
Industrial Applications
| Application | Typical Use |
|---|---|
| Power Generation | SOE event synchronization |
| Thermal Power Plants | Alarm and trip analysis |
| Turbine Systems | Event sequence monitoring |
| Boiler Control | Process disturbance analysis |

Technical FAQs
What does the “-15” designation indicate?
The “-15” identifies the 15-foot cable configuration of the NKTK01 family.
What role does NKTK01-15 play in SOE recording?
It provides the physical connection through which the applicable synchronization signal reaches the associated INFI 90 SOE equipment.
Does the cable determine the timestamp of an event?
No. The cable transfers the synchronization signal. Timestamp generation and SOE event processing are handled by the associated system hardware.
What should be checked if event times are inconsistent?
Check the synchronization source, interface hardware, cable connections, receiving SOE equipment, and system diagnostics. Comparing timestamps from several event sources can help locate the affected section of the timing path.
