  • Status Indication: Front-panel LEDs for power, attention (ATTN), and dual Ethernet port status.
  • Self-Powered: Contains its own internal power supply, simplifying cabinet wiring.

Application Scenarios:

  • Gas turbine and steam turbine exhaust and bearing temperature monitoring.
  • Critical process temperature measurement in oil and gas refineries.
  • Safety system temperature interlocks in hazardous environments.
  • Industrial boiler and heat exchanger monitoring.

Material Composition & Structural Characteristics:

  • Dimensions: Approximately 34 x 18 x 10 cm.
  • Weight: Approximately 4.40 lbs (without packaging).
  • PCB Construction: Multi-layer board with precision analog front-end components.
  • Connectors: Side-mounted Ethernet ports and backplane edge connectors.

Working Principle: The module supplies a precise excitation current to the connected sensors. It measures the resulting voltage drop, calculates the resistance, and converts it to a temperature value using standard RTD curves (e.g., Pt100). The digital temperature values are processed, scaled, and transmitted over the I/O bus to the main controller for display, control, and safety trip logic.

Installation Requirements:

  • Sensor Wiring: Connect sensors using properly insulated cables as per local electrical codes.
  • Terminal Board: Must be paired with the correct compatible terminal board for hazardous area compliance.
  • Mounting: Securely mount the module in the designated I/O slot and engage the extraction levers.
  • Configuration: Define the RTD type, wiring configuration (2-wire, 3-wire, 4-wire), and scaling in the control software.

Usage Precautions:

  • Input Restriction: ONLY connect resistive RTD sensors. Connecting voltage or current sources will damage the module.
  • ESD Protection: Always use ESD precautions when handling the module to protect sensitive analog circuitry.
  • Cable Integrity: Periodically inspect cables for insulation degradation or moisture ingress.
  • LED Diagnostics: Use the ATTN LED to identify channel faults or open RTD conditions.
