Core Functions

1. Multivariable Transmitter Integration: Connects HART multivariable transmitters (Coriolis mass flow, DP with temp compensation) to TDC3000 UCN.

2. Multi‑Parameter Data Acquisition: Captures up to 8 process variables per transmitter (mass flow, density, temperature, pressure).

3. Multidrop Communication: Up to 16 multivariable devices per card, reducing wiring and hardware costs.

4. Digital Configuration & Calibration: Remote setup, calibration, and parameter adjustment for all variables via HART.

5. Enhanced Reliability: Conformal coating protects against dust, humidity, and chemicals in harsh environments.

6. Advanced Diagnostics: Monitors transmitter health, detects open circuit, overrange, variable mismatch, and reports to DCS.

Application Scenarios

• TDC3000/TPS DCS: Primary interface for HART multivariable transmitters in process industries.

• Harsh Process Plants: Chemical, petrochemical, oil & gas, offshore, pulp & paper, wastewater.

• Multivariable Instrumentation: Coriolis flowmeters, DP transmitters with temperature compensation, level transmitters with density.

• High‑Reliability Installations: Humid/corrosive areas where conformal coating extends service life.

• CE‑Compliant Plants: Required for European Union installations.

Compatibility Note

• System Compatibility: Honeywell TDC3000/TPS (UCN network required)

• Field Device Compatibility: HART 5/7 multivariable, Honeywell ST3000 smart transmitters

• Replacement: Direct, drop‑in upgrade for 51304516‑200 (non‑coated); same functionality with conformal coating

• Firmware: Requires TDC3000 firmware Rev 400+ for full HART multivariable support

• Key Difference: 51304516‑250 = Multivariable + CE + Conformal Coating; 51304516‑200 = Multivariable + CE (no coating); 51304516‑150 = Single‑variable + CE + Conformal Coating
