Functional Features:

  • 4-channel isolated input for resistance thermometers
  • Supports Pt100 and JPt100 sensors
  • High accuracy and stability
  • Burnout detection (upper/lower limit)
  • Removable terminal block

Application Scenarios:

  • Temperature monitoring and control
  • Process industries (chemical, food, pharmaceutical)
  • HVAC systems
  • Industrial ovens and furnaces

Performance Parameters:

  • Input Channels: 4
  • Sensor Type: Pt100, JPt100
  • Conversion Speed: 250 ms (all 4 channels)
  • Accuracy: ±0.3%

Material Composition:

  • Precision measurement circuitry
  • Multi-layer printed circuit board
  • Plastic housing
  • Removable terminal block

Structural Features: The unit features a compact 35mm width. The front panel includes a removable terminal block for sensor wiring.

Working Principle: The unit excites the resistance thermometer with a constant current, measures the voltage drop, and calculates the temperature based on the resistance-temperature characteristic. The signal is isolated and converted to digital data for the CPU.

Installation Requirements:

  • Mount on CS1 series CPU rack or expansion rack.
  • Use 3-wire or 4-wire connection for Pt100 sensors to minimize lead resistance errors.
  • Ensure proper grounding.

Usage Notes:

  • Verify the sensor type (Pt100 vs JPt100) matches the configuration.
  • Do not apply voltage to the input terminals.
  • Ensure the wiring is secure to prevent measurement errors.
