Technical Specifications 24VDC power supply, multi-channel high-speed pulse input. Operating temperature: -40℃ ~ +70℃, wide frequency input range.
Functional Features Pulse waveform reshaping, frequency calculation, pulse totalizing, input fault detection.
Application Scenarios Prime mover speed measurement, incremental encoder position acquisition, pulse flow meter monitoring.
Performance Parameters High sampling rate, accurate counting, stable operation under vibration environment.
Structural Characteristics Rack pluggable module, pulse channel running and fault indicators.
Working Principle Input pulse signals are shaped into square waves. The internal counter counts pulses in fixed time window and calculates frequency, then uploads the result to the main processor.
Installation Requirements Shielded twisted pair for pulse wiring, avoid parallel laying with inverter power cables.
Usage Notes Adjust trigger threshold according to pulse amplitude to prevent missing pulses.
