Technical Specifications 24VDC power supply, multi-channel high-frequency pulse input. Operating temperature: -40℃ ~ +70℃, wide frequency measurement range.
Functional Features Pulse waveform shaping, frequency calculation, pulse accumulation counting, signal fault diagnosis.
Application Scenarios Prime mover speed measurement, flow meter pulse acquisition, encoder position tracking.
Performance Parameters High sampling frequency, accurate counting, stable measurement under mechanical vibration.
Structural Characteristics Rack pluggable module, pulse running and fault LED indicators.
Working Principle The module converts input pulse signals into standard square waves, counts pulses within fixed time windows and calculates frequency value, then uploads data to the main processor.
Installation Requirements Shielded twisted pair cable for pulse wiring, avoid parallel arrangement with variable frequency power cables.
Usage Notes Adjust signal threshold according to the actual pulse amplitude, prevent missed counting.
