Key Features

1. High‑Density RTD Input: 16 isolated channels for 3‑wire/4‑wire Pt100 sensors。

2. Full Isolation: Eliminates ground loops and crosstalk in noisy industrial environments。

3. High Precision: ±0.05% accuracy for critical temperature monitoring。

4. Solid‑State Design: No moving parts; conformal coated for dust/moisture resistance。

5. Sensor Fault Detection: Open/short‑circuit RTD detection (<1 second)。

6. Wide Compatibility: Works with standard Pt100 RTDs for diverse industrial applications。

Applications

• Industries: Power generation, petrochemical, oil & gas, pulp & paper, pharmaceuticals, food & beverage。

• System Role: Primary RTD input interface for Honeywell UCN/TDC3000 DCS。

• Use Cases:

  • Precision temperature monitoring in reactors, furnaces, and pipelines。

  • High‑density RTD signal multiplexing in large process plants。

  • Accurate temperature control for critical manufacturing processes。

Installation & Wiring

1. ESD Precautions: Wear anti‑static wristbands and use ESD‑safe surfaces。

2. Power Off: De‑energize the I/O chassis/PM before insertion/removal。

3. Chassis Installation: Insert into a UCN I/O slot and secure with screws。

4. Field Wiring:

   • Connect RTD 3‑wire/4‑wire leads to compression terminals。

   • Use shielded twisted‑pair cable; maintain polarity and cable length consistency。

5. Configuration: Use Experion/TPS tools to set RTD type, range, and scaling parameters。

Maintenance

• Periodic Inspection: Check LED status, terminal tightness, and 24 VDC power。

• Cleaning: Remove dust with a dry, soft cloth; avoid liquids。

• Fault Handling:

  • Verify RTD wire integrity and connection polarity。

  • Check for open/short circuits in field wiring。

  • Use system diagnostics to identify channel/board faults。

Safety Notes

• Perform all work with chassis power disconnected。

• Operate within rated temperature and humidity limits。

• Unauthorized modification or disassembly is prohibited。

• Comply with site ESD and safety procedures。
