ABB Bailey NKST11-15 SOE Time Synchronization Cable

Applications and Precision Event Timing Communication

The ABB Bailey NKST11-15 SOE Time Synchronization Cable is a specialized industrial cable assembly designed for ABB Bailey Sequence of Events (SOE) systems. This cable provides a reliable connection between the SPSET SOE module and the NTST01 termination unit, supporting accurate time synchronization and dependable event timestamp transmission within ABB Bailey Infi 90 distributed control system environments.

The NKST11-15 is widely applied in power generation, chemical processing, oil and gas, and other process automation industries where precise event recording is essential. SOE systems rely on accurate synchronization signals to ensure that alarms, equipment trips, and operational changes are recorded in the correct chronological order for troubleshooting and performance analysis.

Featuring a 15-foot cable length and non-PVC insulation construction, the NKST11-15 provides flexible installation capability for control cabinets, I/O racks, and distributed termination layouts. It is a practical maintenance component for facilities operating ABB Bailey legacy DCS systems that require stable and accurate SOE timing communication.
