ABB NTST01 is a time synchronization termination unit for Harmony Rack and INFI 90 control-system hardware. Its role is defined by the connected module, cable and field or network circuits.
Replacement requires confirmation of the complete model, revision, module pairing, terminal assignments and cabinet installation rather than selection by appearance alone.
The ABB NTST01 may be supplied and supported by Moore Automated according to the stated manufacturer lifecycle and confirmed stock condition.

Interface Functions:
- Sequence-of-events termination
- SPTKM module compatibility
- SPSET module compatibility
- IRIG-B reference input path
- 62.5 kbaud RS-485 synchronization link
NTST01 terminates the IRIG-B DC level-shift input and 62.5 kbaud RS-485 time synchronization link for documented SPTKM or SPSET SOE modules. Verify timing source format, cable, polarity, shielding and module configuration before commissioning.
System Compatibility:
- ABB documents NTST01 for Sequence of Events applications with SPTKM or SPSET modules. Match the module revision and timing cable.
- Match the module cable and hardware revision.
- Verify field or network wiring before commissioning.
It distributes the external time reference used to synchronize event time stamps across Harmony control units.
Installation Guidance:
- Isolate cabinet and field power before wiring.
- Preserve terminal identification and cable routing.
- Complete a functional check before process operation.
Confirm the IRIG-B source format, isolate timing circuits, preserve RS-485 polarity and shielding, connect the specified module cable and validate synchronized event time stamps.
