Technical Specifications 24VDC power supply, analog fuel command input and output. Operating temperature: -40℃ ~ +70℃, adjustable limiting threshold.
Functional Features Fuel command tracking, maximum fuel limiting, fuel ramp rate control, limiting status feedback, fault alarm.
Application Scenarios Gas engine fuel control loops, diesel generator fuel regulation systems, combustion protection cabinets.
Performance Parameters Smooth limiting action, no sudden fuel cut, stable ramp control.
Structural Characteristics Compact pluggable PCB module, limiting status indicator light, isolated analog circuit.
Working Principle The module receives the fuel command signal from the governor. If the command exceeds the preset fuel limit value, it clamps the output signal to the maximum allowable level and sends limiting status to the controller.
Installation Requirements Install between governor and fuel actuator drive module, shielded analog wiring required.
Usage Notes Set fuel limit value matching engine specification, do not arbitrarily increase fuel limit.
