Technical Specifications 24VDC control power; multi-channel speed pulse input; hardware trip circuit; fault event storage function. Operating temperature: -40℃ ~ +85℃.
Functional Features Multi-channel speed signal comparison; independent overspeed trip; fault alarm; circuit self-test and fault latch.
Application Scenarios Gas turbine, gas engine and large genset overspeed safety protection cabinets.
Performance Parameters Ultra-fast trip response, high speed detection accuracy, independent hardware protection channel.
Structural Characteristics Rack pluggable PCB, built-in shielding layer, dedicated terminals for speed signal and trip output.
Working Principle Independently collect multi-channel speed pulse signals, compare measured speed with overspeed threshold. Once exceeding threshold, hardware circuit immediately triggers safety relay to execute unit trip.
Installation Requirements Use shielded cable for speed signal; keep away from strong electromagnetic interference source.
Usage Notes Perform overspeed simulation test before commissioning; cut off power supply before removing board.
