Function and Working Principle
The 900TEK-0101 functions as a central electrical termination interface for HC900 I/O systems.
It is responsible for:
- Terminating multiple field wiring connections in a structured layout
- Providing safe separation between adjacent electrical circuits
- Supporting high-density wiring organization inside control cabinets
- Enabling secure screw-clamp connections for reliable contact
- Allowing modular integration with HC900 I/O modules
It does not process signals; it serves as a passive but critical wiring interface device.
