Temperature Sensor Compatibility

• Supports Pt100, Cu10, Ni100, and Ni120 RTD sensors
• Works with standard resistive sensors and potentiometers
• All RTD elements must be properly isolated from ground
• Module performs automatic temperature linearization
• Converts readings to Centigrade or Fahrenheit units
• Eight independent channels for flexible installation
• 3-wire connection system for improved accuracy

Technical Specifications

• High 14-bit resolution for precise temperature readings
• Update cycle time: 150 + 95 × (active channels) milliseconds
• Excellent CMRR >120 dB at 50Hz/60Hz with 10Ω load
• Strong NMRR >60 dB for noise rejection
• Power dissipation: 1.6 W for efficient operation
• Current consumption: 70 mA from +5V Modulebus

Error Calculation and Accuracy

• Error depends on field cable resistance
• Calculation formula: Rerr = R × (0.005 + ΔR/100)
• Temperature error in °C: Terr°C = Rerr / (R0 × TCR)
• Temperature error in °F: Terr°F = Terr°C × 1.8
• Optimized for long cable runs
• Compensates for wire resistance effects
• Maintains accuracy across temperature ranges
