Technical Specifications 24VDC power input; high-current drive channel; integrated overcurrent, short-circuit and thermal protection circuits. Operating temperature: -40℃ ~ +85℃.
Functional Features Control signal power amplification; real-time drive channel monitoring; automatic fault protection; fault alarm output.
Application Scenarios Fuel and gas actuator closed-loop control circuits for gas engines and diesel engines.
Performance Parameters Fast signal response, stable continuous output, quick protection trigger when overload occurs.
Structural Characteristics Rack pluggable PCB; isolated terminal blocks for power loop and weak signal loop.
Working Principle The board receives low-level analog or digital command from main controller, amplifies signal power through internal power circuit, outputs drive current to actuator coil to adjust valve stroke.
Installation Requirements Arrange installation close to actuator to reduce signal attenuation; separate power wiring and weak control wiring.
Usage Notes Test actuator coil resistance to exclude short-circuit risk before power on; anti-static protection during disassembly.
