Technical Specifications 24VDC power supply, magnetic pickup signal input, square wave pulse output. Operating temperature: -40℃ ~ +70℃.
Functional Features Weak pulse amplification, waveform shaping, noise filtering, signal amplitude stabilization, open sensor detection.
Application Scenarios Diesel engine speed measurement, gas engine speed feedback loop, small prime mover governor systems.
Performance Parameters Wide input frequency range, stable square wave output, good anti-interference capability.
Structural Characteristics Small PCB board, speed signal status indicator, screw terminal wiring.
Working Principle The board receives low-amplitude AC pulse signals from the magnetic pickup sensor, filters electromagnetic noise, amplifies the signal and converts it into standard square wave pulses for the governor.
Installation Requirements Install close to the speed probe, use shielded twisted pair cable for sensor wiring.
Usage Notes Check sensor air gap regularly, replace the board if pulse signal loss occurs.
