Technical Specifications 24VDC power supply; pulse signal input from magnetic pickup; waveform shaping and amplitude amplification circuit. Operating temperature: -40℃ ~ +70℃.
Functional Features Weak pulse signal amplification; waveform shaping; noise filtering; overvoltage protection for sensor input.
Application Scenarios Gas engine, diesel genset speed measurement and governing systems.
Performance Parameters High signal sensitivity, stable pulse output, strong anti-interference capability.
Structural Characteristics DIN rail mount metal housing, pluggable terminals, onboard signal filter circuit.
Working Principle Weak sine wave pulse from magnetic pickup enters the module. The circuit amplifies the signal, filters interference noise and converts sine wave into square wave pulse signal for governor speed calculation.
Installation Requirements Install near speed sensor; use shielded twisted pair for sensor wiring; separate from high current cables.
Usage Notes Check pulse waveform during commissioning; inspect wiring insulation and shielding integrity periodically.
