ABB NTST01 is an evidence-bounded sequence-of-events time-synchronization termination unit in the Bailey INFI 90 / Harmony Rack installed-base context. ABB identifies NTST01 as the termination unit for IRIG-B and RS-485 time-synchronization paths in Harmony sequence-of-events applications.
- Application: Harmony sequence of events
- Time inputs / outputs: IRIG-B input; RS-485 synchronization
- RS-485 rate: 62.5 kbaud
- Cable: Twinaxial
System role: It couples the time-synchronization input/output path used by INTKM01 and supported SOE architecture. The page publishes only functions and ratings stated by the cited ABB material; sibling and successor data are not transferred. Architecture boundary: ABB specifies DC level-shift IRIG-B input, a 62.5 kbaud RS-485 synchronization path and twinaxial inter-cabinet cabling for the documented design. Exact cable, termination, firmware, revision and host dependencies must be checked against the physical assembly and approved project drawings. For maintenance, migration or replacement work, verify identity, companion hardware, wiring, addressing, power, network settings and commissioning tests before returning the loop or node to service. Current formal lifecycle phase, origin, HS code, dimensions and logistics weight remain HOLD without exact ABB evidence.
Important Notice: Verify the complete ABB NTST01 nameplate, revision and installed-system documentation before use.

Installed-base maintenanceSupports evidence-led identification and replacement planning for ABB NTST01.
System documentationProvides a source-traceable boundary for rack, network, I/O and termination records.
Commissioning reviewGuides pre-power checks, companion-module verification and controlled functional testing.
Migration assessmentSeparates exact-model facts from successor, sibling and family-level information.
Read and follow the exact ABB documentation and host-equipment instructions before work. Verify the complete physical nameplate and system configuration.
1Verify the complete ABB NTST01 nameplate, revision and installed-system documentation before use.
2The published isolation and distance limits apply only to the cited SOE architecture and do not authorize arbitrary cable, topology or live-work changes.
3De-energize and follow the site's approved electrical and process-safety procedure before disturbing hardware or field wiring.
4Back up controller, network, I/O, addressing and configuration data before replacement or firmware work.
5Verify every companion module, termination unit, cable, connector and power source from approved drawings.
6Do not copy electrical, communication, mechanical or lifecycle values from a related model or successor.
7Perform a documented loop, network or functional test and confirm alarms and fail states after work.
8Current formal lifecycle phase, origin, HS code, dimensions and logistics weight remain HOLD without exact ABB evidence.
