Working Principle:
Analog signals from 8 channels are multiplexed into a 16-bit A/D converter. The on-board microcontroller applies cold junction compensation (TC), polynomial linearization (TC/RTD), and scaling. Processed digital values are transmitted to the FAST/TOOLS controller via the Vnet/IP backbone. HART communication uses FSK modulation superimposed on the 4–20mA signal at 1200 bps.

Advantages & Highlights:

• HART 7 compliant enables intelligent field device management
• Universal input coverage eliminates need for multiple module types
• 500V AC isolation ensures signal integrity in electrically noisy environments
• Per-channel diagnostics (burnout, open circuit, short circuit)
• Firmware variant S00 optimized for specific application profiles (differs from S01 in default parameter sets)

Applicable Industries:
Oil & Gas, Chemical, Petrochemical, Power Generation, Water & Wastewater, Pharmaceutical, Mining

Installation Requirements:

• Install in FAST/TOOLS I/O station
• Use shielded twisted-pair cables appropriate for signal type
• For TC: use extension-grade thermocouple wire; for RTD: use 3-wire or 4-wire configuration
• Ground shields at control room end only
• Verify slot address in FAST/TOOLS Engineering Station (FES)
• Ambient: -10°C to +60°C, humidity: 10–85% RH (no condensation)

Usage Precautions:

• Maximum input voltage: 50V DC on any channel
• For 3-wire RTD: match wire colors to terminal markings exactly; mismatch causes up to 2°C error
• HART requires 250 Ω resistor in the loop (integrated in most FAST/TOOLS I/O stations)
• Do not hot-swap unless the I/O station explicitly supports it
• Annual calibration using Yokogawa CA150 or CA750 calibrator recommended
