Technical Specifications 24VDC power input; high-current drive output channel; integrated short-circuit, overcurrent and thermal protection circuits; industrial PCB layout. Operating temperature: -40℃ ~ +85℃.
Functional Features Low-level control signal power amplification; real-time drive channel status monitoring; automatic overcurrent and short-circuit protection; fault alarm output for channel abnormality.
Application Scenarios Prime mover fuel/gas actuator closed-loop control circuits for gas engines and diesel engines.
Performance Parameters Fast signal response speed; stable continuous drive output; reliable automatic protection when overload occurs.
Structural Characteristics Plug-in printed circuit board, rack mounting design; separated terminal blocks for power circuit and weak signal circuit.
Working Principle The board receives low-magnitude digital or analog control command from the main controller. The internal power circuit amplifies the signal power and outputs drive current to the actuator coil, so as to adjust the actuator stroke and control fuel or gas flow.
Installation Requirements Install the board as close as practical to the actuator to reduce signal attenuation; separate high-power drive wiring and weak control signal wiring.
Usage Notes Measure actuator coil resistance to confirm no short circuit before powering up the driver board; apply anti-static protection during board replacement.
