Structural Features:

• Plugs into FTEB (Field Termination and Electronics Base)底座

• Series C form factor with patented heat channeling design

• Supports redundant implementation for no-single-point-of-failure solutions

Working Principle:
For temperature inputs, the module receives微弱 voltage/resistance signals from thermocouples and RTDs, amplifies them through precision signal conditioning circuits with cold junction compensation, and converts them to digital values via a 16-bit ADC. For 4-20 mA inputs, the module converts current to voltage through a 250 Ω resistor, performs A/D conversion, and simultaneously extracts HART digital communication packets superimposed on the analog loop.

Advantages & Strengths:

• ±0.05% accuracy – for a 100°C temperature signal, error is less than 0.05°C

• HART integration enables predictive maintenance – smart device diagnostics appear directly on DCS画面

• Redundant power supply ensures high availability

• SIL2 certification (IEC 61508) allows use in safety instrumented systems (SIS)

• 16-channel capacity with full isolation

Applicable Industries:

• Refining & Petrochemical: Reactor temperature, column level, pipeline pressure monitoring

• Power Generation: Boiler and turbine parameter measurement

• Pharmaceutical: Critical temperature control in production processes

• General Process Industries: Any application requiring high-accuracy temperature or 4-20 mA signal acquisition

Model Series: Experion PKS C300 I/O Series

Installation Requirements:

• Insert into FTEB (Field Termination and Electronics Base)底座 in C300 I/O rack

• Control room installation only (IP20)

• Ensure redundant 24 VDC power supply through I/O backplane

• Proper wiring for 2-wire vs. 4-wire transmitter configurations

Usage Precautions:

• Monitor diagnostic LEDs for open circuit, short circuit, and over-range conditions
