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 measurement.

5. Compact & Lightweight: 10×6×11 cm, 0.28 kg; saves cabinet space vs. standard Size B FTA。

6. Backplane‑Powered: Eliminates external power supplies.

Application Scenarios

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

• Temperature Measurement: PT100/PT1000 RTDs for reactors, furnaces, pipelines, storage tanks.

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

• Space‑Constrained Cabinets: Ideal for compact or densely populated I/O cabinets.

Compatibility Note

• Form‑factor: Compact UCN FTA (smaller than 51304477‑100 Size B).

• System Compatibility: Honeywell TDC3000/TPS and Experion PKS (via UCN AI IOP).

• Key Difference from 51304477‑100: 51304477‑150 is ultra‑compact (100×60×110 mm, 0.28 kg); 51304477‑100 is Size B (135×85×55 mm, 0.75 kg)。
