Technical Specifications 24VDC power supply; multi-channel speed frequency signal input, relay trip output. Operating temperature: -40℃ ~ +70℃.
Functional Features Multi-channel speed monitoring; overspeed judgment; trip relay drive; fault alarm and record.
Application Scenarios Gas turbine, large diesel engine and generator overspeed protection.
Performance Parameters High speed detection accuracy, ultra-fast trip response, redundant signal processing.
Structural Characteristics Metal DIN rail housing, LED fault indicator, screw type wiring terminals.
Working Principle Simultaneously collect multiple speed pickup signals, compare with overspeed threshold, trigger trip relay when the speed exceeds the set value.
Installation Requirements Adopt independent speed sensor wiring, separate trip circuit from ordinary control circuit.
Usage Notes Regularly perform trip function test; prohibit arbitrarily changing overspeed threshold parameters.
