Technical Specifications 24VDC power supply; pulse speed input; analog and digital output channels; on-board EMC filter circuit. Operating temperature: -40℃ ~ +85℃.
Functional Features Speed closed-loop PID control; speed setpoint adjustment; overspeed monitoring; channel fault diagnosis.
Application Scenarios Gas engine and diesel engine speed governing control cabinets.
Performance Parameters Fast response to speed deviation, high governing precision, stable operation under vibration environment.
Structural Characteristics Rack pluggable PCB, metal shielding structure, onboard signal terminals.
Working Principle The board compares actual rotational speed feedback with target setpoint, calculates control output via PID algorithm, and sends command to actuator driver to adjust fuel/gas valve opening.
Installation Requirements Install in ventilated dust-proof cabinet; shielded cable for speed pulse signal wiring.
Usage Notes Check speed signal waveform during commissioning; implement anti-static protection during replacement.
