INTKM01 | ABB Bailey | Time Keeper Master Module

Description

The ABB Bailey INTKM01 is a Time Keeper Master Module for the Infi 90 and Symphony Harmony systems. Its critical role is to establish and maintain a single, synchronized "System Time" across all processing modules, operator consoles, and data loggers within the control network. 

Specifications

• Model Number: INTKM01
• Compatibility: Infi 90, Net 90, and Symphony Harmony systems.
• Accuracy: Maintains high-precision internal clock timing.
• External Sync: Supports synchronization via external time sources (such as GPS or IRIG-B signals).
• Battery Backup: Includes an onboard battery to maintain time and date settings during a complete system power loss.
• Power Requirements: +5 VDC from the system backplane.
• Weight: 0.3 kg (approx. 0.66 lbs).
• Shipping Weight: 1.5 kg.

Features

• Network-Wide Synchronization: Periodically broadcasts a time-sync signal across the Plant Loop or Cnet, correcting the internal clocks of all other modules to prevent "clock drift."
• Reliable Time-Stamping: Essential for regulatory compliance and troubleshooting, ensuring that an alarm triggered in Rack A can be precisely compared to an action in Rack B.
• Daylight Savings Management: Can be configured to automatically adjust for seasonal time changes, preventing manual intervention and data gaps.
• Fault Tolerance: In systems with redundant INTKM01 modules, the "backup" module monitors the "primary" and takes over time-keeping duties seamlessly if a failure occurs.
• Visual Status: Features front-panel LEDs that indicate whether the module is acting as the Master, if it is synchronized to an external source, and the health of the backup battery.
• Event Correlation: Works in tandem with the INSEM01 (Sequence of Events Master) to provide the baseline time needed for 1-millisecond resolution event logging.
