Product Overview
The ABB Bailey NKTK11 INFI 90 SOE Time Synchronization Cable is a synchronization cable used in ABB Bailey INFI 90 Sequence of Events (SOE) applications.
SOE systems require a common time reference to establish the chronological relationship between alarms, trips, status changes, and other control-system events. The NKTK11 provides the physical connection required within the applicable synchronization path.
The NKTK11 uses an optional cable-length configuration for INFI 90 installations with different equipment arrangements. It functions as a passive interconnection component rather than an independent timing or event-processing device.

Working Principle
The NKTK11 carries synchronization information between the applicable timing source and receiving equipment.
Time Reference → Synchronization Interface → NKTK11 → SOE Hardware → Event Timestamping
The synchronization equipment establishes the common time reference, while the cable transfers the timing signal to the associated SOE hardware.
The synchronized SOE system can then associate detected events with the common time reference, allowing events from different system points to be arranged chronologically.

Technical FAQs
How does synchronized timing help identify the initiating event during a trip?
A common time reference allows events from different system points to be compared on the same timeline. This can help distinguish the initial event from subsequent alarms, interlocks, and equipment responses.
When is an optional-length NKTK11 configuration useful?
It is useful when the distance between the relevant synchronization interfaces varies between INFI 90 installations. The cable can therefore be matched to the physical arrangement of the associated equipment.
What information can engineers obtain from synchronized SOE records?
SOE records can show the timing and sequence of discrete events, including equipment state changes, alarms, trips, and other status transitions. This information is useful for reconstructing operating sequences.
What should be evaluated when replacing an NKTK11 in an existing system?
The connection points, cable routing, synchronization status, and resulting SOE timestamps should be checked. The replacement should also maintain the intended timing path between the associated INFI 90 synchronization equipment.
