Sequence-of-events timing-link hardware
Verification-led content for maintenance, replacement planning and industrial spare procurement.
Product Summary
ABB Bailey NTST01 is a time synchronization termination unit used in the Harmony sequence-of-events architecture. ABB documentation shows it in the synchronization path between a satellite receiver, time-keeping hardware and Harmony control-unit cabinets. The data sheet identifies an IRIG-B input in DC level-shift format and an RS-485 time-synchronization output operating at 62.5 kbaud through NTST01. It also specifies a twinaxial synchronization link and documented isolation and cable-distance limits. The unit is relevant to event-timing maintenance, cabinet-link troubleshooting and planned spares. Before ordering, confirm the time source, INTKM01 or IMSET01 arrangement, cabinet topology, link cable, termination position, revision and original labels.

System Relationship
Use this sequence only as a procurement check. The installed drawings and product labels define the actual wiring, cable and revision requirements.
Verified Functions
ABB documents IRIG-B in DC level-shift format through NTST01.
RS-485 time synchronization is documented at 62.5 kbaud.
The published data sheet identifies twinaxial cable for the synchronization link.
Published isolation is 1,000 VAC at 50 Hz and 2,000 V peak for a 1.2/50 microsecond pulse.
The data sheet lists 4,000 m between HCU cabinets and 40,000 m from the server node to the farthest HCU cabinet.
Use Cases
Harmony sequence-of-events time synchronization from a documented satellite receiver.
Time-link termination associated with INTKM01 or IMSET01 hardware.
Maintenance of twinaxial synchronization links between Harmony control-unit cabinets.
Planned spares for installed NTST01 timing infrastructure.
Verify the complete NTST01 code, IRIG-B source, INTKM01 or IMSET01 arrangement, synchronization direction, twinaxial cable, cabinet sequence, termination position, grounding, hardware revision and original label photographs.
Buyer Questions
Q1.Is NTST01 currently available?
Availability is checked against the required quantity and NEW condition during quotation preparation.
Q2.What timing formats are documented?
The ABB data sheet identifies IRIG-B DC level-shift input and RS-485 synchronization output through NTST01.
Q3.Which cable is used for the synchronization link?
ABB documents twinaxial cable; confirm the installed cable and cabinet topology before ordering.
Q4.Can the published maximum distances be applied automatically?
No. They are system-level limits and must be reviewed with the actual node count, topology and installation conditions.
Q5.How do I confirm compatibility?
Provide the time source, associated modules, cabinet diagram, cable information and clear NTST01 label photographs.
Q6.What warranty is provided?
NTST01 is offered with 1 year warranty under the written quotation terms.
