Technical Specifications 24VDC power supply; motor drive for potentiometer adjustment; analog resistance/voltage output as speed reference. Operating temperature: -40℃ ~ +70℃.
Functional Features Remote speed raise/lower adjustment; manual backup adjustment; position holding after power off; end-of-travel limit protection.
Application Scenarios Steam turbine, diesel and gas engine governor remote speed setting control.
Performance Parameters Smooth adjustment, stable reference output, reliable motor operation and long service life.
Structural Characteristics Metal housing, built-in small servo motor and precision potentiometer, input and output wiring terminals.
Working Principle When receiving raise or lower contact command, internal motor drives potentiometer shaft to change resistance value. The output analog signal is sent to governor as speed setpoint reference.
Installation Requirements Install in control cabinet; separate low-level reference wiring and high-power cables.
Usage Notes Check motor and potentiometer wear during overhaul; verify limit stop function before operation.
