Function and Working Principle
The 900RTC-L225 cable functions as a signal transmission link between HC900 control system components.
It is responsible for:
- Transmitting low-voltage I/O signals between modules and RTPs
- Reducing direct field wiring inside control cabinets
- Ensuring stable and noise-resistant signal communication
- Supporting modular plug-and-play system design
- Maintaining signal integrity through shielding and grounding
The cable does not process signals; it provides reliable physical connectivity only.
