Description
Overview
The INTKM01 Time Keeper Master Module is a synchronization control component developed for ABB Bailey Infi 90 and Net 90 distributed control systems. The module provides centralized plant-wide time coordination for sequence-of-events recording and synchronized process monitoring applications.
Designed for integration with the NTST01 synchronization interface, the module receives IRIG-B reference signals and distributes high-accuracy timing data through RS-485 communication links to connected system cabinets and event management nodes.
The INTKM01 is commonly applied in power generation, process automation, and critical industrial environments where precise event timestamping and coordinated control operations are required.
