Core Functions

1. 16-Channel High-Precision Acquisition: 16-bit resolution, ±0.075% accuracy for 4–20mA/1–5V field signals。

2. Redundant Operation: 1:1 redundancy for critical loops; automatic failover on primary fault, bumpless transfer.

3. Integrated STI Termination: Built-in compression terminals eliminate external FTA, reduce wiring complexity and cost。

4. Signal Conditioning: On-board filtering, amplification, linearization for noisy industrial environments.

5. Comprehensive Diagnostics: Detects overrange, open/short circuit, module health; reports to DCS.

6. Hot-Swappable: Online replacement in redundant mode, no system shutdown.

Application Scenarios

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

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

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

• Honeywell TDC3000 / Experion PKS: Native compatibility for seamless integration.
