Main Components

A typical DPG-2401-002 controller includes:

  • Microprocessor CPU
  • LCD Display
  • Keypad Interface
  • Main PCB
  • Power Supply Circuit
  • Governor Output Driver
  • Speed Signal Input Circuit
  • Communication Port
  • Terminal Block

Working Principle

The controller receives an engine speed signal from the magnetic pickup mounted near the flywheel.

It continuously compares the actual engine speed with the programmed reference value and calculates the required correction using a PID control algorithm.

The controller then sends an output signal to the electronic actuator, adjusting the fuel rack position to maintain constant engine speed even during rapid load changes.
