Core Functions

1. 16‑Channel RTD Input: Precision multiplexing for PT100/PT1000 temperature sensors.

2. Low‑Level Signal Conditioning: Amplification, filtering, and cold‑junction compensation for RTDs.

3. Basic Isolation: 500 VAC channel‑to‑backplane isolation protects DCS from field faults.

4. High Accuracy & Resolution: 16‑bit resolution with ±0.05% FS accuracy for precise temperature control.

5. Backplane‑Powered: Eliminates external power supplies; draws power from UCN backplane.

6. Fault Detection: Per‑channel open/short circuit monitoring for RTD sensor diagnostics.

Application Scenarios

• Process Industries: Chemical, petrochemical, power generation, pulp & paper (precision temperature monitoring).

• Temperature Measurement: PT100/PT1000 RTD sensors for reactors, furnaces, pipelines, and storage tanks.

• Legacy DCS Systems: Replacement/expansion for TDC3000/TPS needing 16‑channel RTD input FTA.

• Size B UCN Cabinets: Standard UCN form factor for compatibility with existing I/O cabinet layouts.

Compatibility Note

• Form‑factor compatible with Size B UCN FTAs.

• Functionally compatible with Honeywell TDC3000/TPS and Experion PKS (via UCN AI IOP).

• Key Difference from 51304453/76 Series: 51304477‑100 is RTD‑specific low‑level input FTA; others are analog input/output for standard 4–20 mA/1–5 V signals.
