Technical Specifications 24VDC power supply; speed pulse input channel; analog and discrete I/O interfaces; communication port for parameter configuration. Operating temperature: -40℃ ~ +85℃.
Functional Features PID closed-loop speed regulation; load limiting control; overspeed monitoring; fault self-diagnosis and historical event storage.
Application Scenarios Steam turbine, gas engine and diesel genset governing cabinets.
Performance Parameters Rapid dynamic response during load fluctuation, high speed control accuracy, reliable long-term continuous operation.
Structural Characteristics Rack pluggable printed circuit board, metal shielding layer, onboard wiring terminals.
Working Principle The board collects real-time rotational speed pulse signals, compares measured speed with target setpoint, executes PID algorithm and outputs control commands to actuator driver for fuel/gas flow adjustment.
Installation Requirements Install in ventilated dust-proof cabinet; adopt shielded twisted pair cable for speed pulse signal transmission.
Usage Notes Check speed signal waveform during commissioning; anti-static protection required for disassembly and replacement.
