Core Functions

1. High-Precision Analog Acquisition: Converts 4–20mA/1–5V field signals to digital data with 16-bit resolution and ±0.05% accuracy.

2. Redundant Operation: Supports 1:1 redundancy for critical loops; automatic failover on primary module fault.

3. Signal Conditioning: Built-in filtering, amplification, and linearization for noisy industrial environments.

4. STI Termination: Integrated compression terminals eliminate external FTA modules, reducing wiring complexity.

5. Fault Diagnostics: Real-time monitoring of input overrange, open/short circuit, and module health; reports to DCS via HPM bus.

6. Hot-Swappable: Can be replaced online without system shutdown (redundant mode).

Application Scenarios

• Process Control Industries: Chemical, petrochemical, oil & gas, power generation (thermal/ nuclear), pulp & paper.

• Critical Parameter Monitoring: Flow, pressure, temperature, level, and vibration measurements from transmitters/sensors.

• Redundant DCS Systems: Safety-critical loops requiring high availability (e.g., reactor control, boiler protection).

• Honeywell TDC3000 / Experion PKS: Native compatibility with Honeywell’s flagship DCS platforms for seamless integration.
