Technical Specifications 24VDC power supply, multi-channel RTD input, support 2-wire, 3-wire and 4-wire wiring. Operating temperature: -40℃ ~ +70℃.
Functional Features RTD resistance sampling, resistance-temperature conversion, open and short circuit detection, digital filtering.
Application Scenarios Generator winding temperature monitoring, bearing temperature protection, engine temperature measurement.
Performance Parameters High temperature precision, low long-term drift, wire resistance compensation function.
Structural Characteristics Rack pluggable module, independent LED indicator for each temperature channel.
Working Principle Constant excitation current is supplied to the RTD sensor. The module measures resistance change caused by temperature fluctuation and calculates temperature value through built-in linear algorithm.
Installation Requirements Use dedicated RTD shielded cables, select 3-wire or 4-wire connection for high-precision measurement.
Usage Notes Set sensor type for each channel, complete calibration regularly.
