6. Conformal Coating: Dust/moisture protection for harsh industrial environments.

7. LED Status Indicators:

   • PWR (Green): Steady = power normal

   • RUN (Green): Flashing = module operating normally

   • FLT (Red): On = communication fault or error

5. Application Range

• Target Systems: Honeywell Experion PKS, TDC3000, UCN DCS

• Industries: Power generation, chemical, petroleum refining, water treatment, and other process industries.

• Function: Central communication hub for controllers, I/O, and HMI/SCADA layers.

6. Compatibility Notes

• Backward Compatible: Works with existing UCN racks and R200-series modules.
