Key Features

1. Size B (12 in) Form Factor: Fits standard UCN I/O chassis Size B slots.

2. Red Screw Terminals: High‑visibility red compression screws for easy wiring ID and maintenance.

3. Conformal Coating: Protects against moisture, dust, and chemicals for harsh industrial environments.

4. Redundancy Support: Works with standard and redundant MU‑PAIH03 / MC‑PAIH03 IOPs.

5. CE Compliance: Meets EU EMC directives.

6. 16‑Channel Density: High‑density voltage input termination, saving cabinet space.

Applications

• Process Industries: Chemical, petrochemical, power generation, oil & gas, pulp & paper.

• System Role: Field termination & signal conditioning for high‑level analog inputs in Honeywell DCS.

• Typical Uses:

  • Connecting voltage‑output pressure, flow, level, and temperature transmitters.

  • Isolating and routing analog signals to HLAI IOPs.

  • High‑precision data acquisition in humid/dusty/chemically exposed areas.

Installation & Wiring

1. ESD Protection: Use anti‑static wristbands and ESD‑safe surfaces.

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

3. Chassis Installation:

   • Insert FTA into Size B slot in UCN I/O chassis.

   • Secure with mounting screws.

   • Connect 50‑pin ribbon cable to mating IOP.

4. Field Wiring:

   • Use shielded twisted‑pair cable for voltage signals.

   • Connect signal positive/negative to designated red compression terminals.

   • Ground shields at one end to avoid ground loops.

5. Configuration: Set channel ranges (0–10 V, ±10 V, etc.) via Experion PKS/TPS software.

Maintenance

• Inspection: Check red terminal tightness, cable connections, and 24 VDC power.

• Cleaning: Use dry, soft cloth; avoid liquid cleaners.

• Troubleshooting:

  • Verify wiring polarity and integrity.

  • Check for short circuits or ground faults.

  • Use system diagnostics to isolate faulty channels.

Safety Notes

• Disconnect chassis power before installation/maintenance.

• Operate within rated temperature/humidity limits.

• Do not modify or disassemble (voids warranty).

• Comply with site ESD and safety procedures.
