Function and Working Principle
The NKTT01 cable is used to complete and stabilize communication loops within ABB Bailey INFI-Net systems.
In operation, communication signals travel between system nodes through the network loop. The termination cable ensures that the communication path is properly closed and stabilized, preventing signal reflection or disruption. This helps maintain reliable data transmission across the entire control network.
The cable works together with termination units to support stable and continuous communication between distributed control modules.
