Technical Specifications 24VDC power supply, multi-channel RTD input. Operating temperature: -40℃ ~ +70℃, support 2-wire, 3-wire and 4-wire RTD wiring modes.
Functional Features RTD signal sampling, resistance-to-temperature conversion, open-circuit and short-circuit fault detection, digital filtering, temperature data upload.
Application Scenarios Engine cylinder temperature monitoring, bearing temperature protection, generator winding temperature measurement.
Performance Parameters High temperature measurement precision, low long-term drift, compensation for wire resistance error.
Structural Characteristics Rack pluggable module, independent LED status indicator for each temperature channel.
Working Principle The module sends constant excitation current to the RTD sensor, measures the resistance change caused by temperature variation, and converts the resistance signal into temperature value through built-in linearization calculation.
Installation Requirements Use matched RTD shielded cables, adopt 3-wire or 4-wire wiring for high-precision measurement.
Usage Notes Set sensor type and wiring mode for each channel, calibrate temperature channels periodically.
