Technical Specifications 24VDC power supply, multiple channels of magnetic pickup pulse input. Operating temperature: -40℃ ~ +70℃, hardware trip circuit with latching function.
Functional Features High-frequency speed pulse sampling, overspeed threshold comparison, hard relay trip output, fault self-test, trip status latch.
Application Scenarios Heavy-duty gas turbines, steam turbines, critical generator sets requiring SIL overspeed protection.
Performance Parameters Ultra-short trip reaction time, independent hardware logic, high safety integrity, strong vibration resistance.
Structural Characteristics Rack pluggable heavy-duty safety module, trip, fault and channel status indicator lights.
Working Principle The module independently samples pulse signals from redundant speed sensors, calculates real-time rotational speed by measuring pulse frequency. When the speed exceeds the preset trip setpoint, the hardware circuit immediately activates the trip relay and locks the trip state until manual reset.
Installation Requirements Use separate speed sensor cables independent of governor speed wiring, implement safety grounding strictly.
Usage Notes Complete overspeed calibration and functional test after installation, do not bypass the trip loop in routine operation.
