Description

The INTKM01 Time Keeper Master module provides time information to the INSEM01 module

and to the rest of the distributed SOE system through the time synchronization link.

The INTKM01 module connects to an external receiver using IRIG-B time code link. The module transmits absolute time to the rest of the system using the RS-485 time synchronization link.

The INTKM01 module cable connects to an NTST01 termination unit. In this case, the termination

unit provides the connection point for the external receiver signals and also the time synchronization link.

Applications

Thermal and hydroelectric power plants: Used for generator trip analysis to ensure consistent timestamps across all protection nodes, enabling the reconstruction of the fault chain.

Oil and gas refineries: Monitor critical alarm sequences in complex process flows.

Large chemical plants: Provide accurate process monitoring time bases in continuous production processes.

Competitive Advantage

High-precision synchronization: Eliminates the "clock drift" problem common in distributed systems, improving SOE resolution.

Smooth evolution: As part of ABB's "Worry-Free Evolution" strategy, it is perfectly compatible with legacy Infi 90 racks, facilitating low-cost upgrades for factories.

High integration: Time synchronization can be achieved in a single rack or across racks (supporting distances up to 40,000 meters) without the need for complex external timing servers.

Maintenance Recommendations

Regular Battery Check: It is recommended to replace the internal lithium battery every 3-5 years to prevent loss of real-time clock during power outages.

Environmental Monitoring: Ensure the module is installed in an IP20-rated rack, maintain humidity between 5% and 95% (non-condensing), and clean dust regularly.

Firmware Updates: Update relevant firmware during system overhauls according to ABB's lifecycle update recommendations (such as FPGA amendments) to improve interference immunity.
