Technical Specifications 24VDC power supply, multi-channel high-speed pulse input. Operating temperature: -40℃ ~ +70℃, wide pulse frequency range.
Functional Features Pulse shaping, high-speed counting, frequency calculation, pulse signal filtering, input channel fault detection.
Application Scenarios Pulse flow meter signal acquisition, encoder position measurement, auxiliary high-frequency pulse monitoring.
Performance Parameters High pulse sampling rate, accurate counting, stable measurement under vibration environment.
Structural Characteristics Rack pluggable module, pulse channel running and fault indicator lights.
Working Principle The module shapes input pulse signals into square waves, counts pulse quantity within fixed time window and calculates frequency, then uploads counting and frequency results to the main processor.
Installation Requirements Use shielded twisted pair cables for pulse signals, avoid parallel laying with inverter power cables.
Usage Notes Adjust pulse threshold according to signal amplitude, prevent missing pulses at low signal level.
