Technical Specifications 24VDC power supply, multi-channel high-frequency pulse input. Operating temperature: -40℃ ~ +70℃, wide frequency measurement range.
Functional Features Pulse waveform reshaping, frequency calculation, pulse accumulation counting, sensor fault detection.
Application Scenarios Prime mover speed measurement, encoder position tracking, pulse flow meter monitoring.
Performance Parameters High sampling rate, accurate counting, stable measurement under vibration environment.
Structural Characteristics Rack pluggable module, pulse running and fault LED indicators.
Working Principle The module shapes input pulses into standard square waves, counts pulses within fixed time windows and calculates frequency value, then uploads data to the main processor.
Installation Requirements Adopt shielded twisted pair cables for pulse signals, avoid parallel laying with inverter power cables.
Usage Notes Adjust trigger threshold according to actual pulse amplitude to avoid missing pulses.
