FAQ

Q: What replaces the INSEM01?
A: The INSEM01 has been officially replaced by the INSEM11, which offers continued support for legacy system migration and maintenance strategies.

Q: How does INSEM01 achieve time synchronization?
A: The INSEM01 synchronizes with the INTKM01 Time Keeper Master module and can also accept external time inputs from satellite receiver systems (SRS) or GPS clocks.

Q: What is the maximum event resolution?
A: The INSEM01 provides ±100 μs time accuracy for digital input transitions, enabling precise sequence-of-events analysis.

Installation Guide

1. Install INSEM01 into an INFI 90 MMU rack slot or DIN rail.
2. Connect digital input signals from field devices to the termination unit.
3. Wire INFI-NET or Cnet communication cables to the network interface.
4. Connect time synchronization cable from INTKM01 Time Keeper Master.
5. Configure event trigger parameters and time window settings via engineering software.
6. Verify timestamp accuracy by injecting known test signals.

Selection Tips

• Replacement Path: For new installations, consider the INSEM11. For legacy maintenance, the INSEM01 remains fully functional.
• Time Source: Ensure a reliable external time source (GPS/SRS) is available for system-wide synchronization.
• Input Count: 32 digital inputs per module; scale quantity to match your SOE monitoring requirements.
