4. Key Features

1. 16‑Channel Enhanced Isolation: Each channel is galvanically isolated from chassis and other channels, eliminating ground loops.

2. Software‑Configurable Ranges: Select mA/V ranges via Honeywell Process Control Designer.

3. High Noise Rejection: Upgraded filtering for electrical interference in high‑noise plants.

4. Hot‑Swappable: Online replacement without system shutdown.

5. LED Status Indicators:

   • PWR (Green): Steady = power normal

   • RUN (Green): Flashing = module active

   • FLT (Red): On = input fault/diagnostic error

5. Application Range

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

• Industries: Power, chemical, oil & gas, refining, water treatment.

• Function: Monitor transmitters (pressure, flow, level, temperature) via 4–20 mA/0–10 V.

6. Installation Instructions

1. Power off the rack before insertion/removal.

2. Insert into standard UCN slot and secure.

3. Use shielded twisted‑pair cable for field inputs.

4. Route cables away from high‑voltage lines.

5. Ground shields at one end only to avoid loops.

7. Maintenance Notes

• Inspect connections quarterly; clean with dry cloth only.

• Avoid harsh solvents; use only genuine Honeywell spares.

• If FLT LED is on, check field wiring, input range, and shunt resistors.

8. Safety Requirements

• All wiring/maintenance must be done with power off.

• Do not exceed rated voltage/temperature.

• Do not disassemble the module.
