Technical Specifications 24VDC power supply, compatible with magnetic pickup pulse signals. Operating temperature: -40℃ ~ +70℃, independent hardware trip circuit.
Functional Features Speed pulse shaping, overspeed threshold comparison, hard trip relay output, fault self-test, trip status latch.
Application Scenarios Gas turbine overspeed protection, diesel engine safety trip loop, high-risk rotating machinery protection.
Performance Parameters Ultra-fast trip response, independent hardware logic, high safety integrity level.
Structural Characteristics Heavy-duty pluggable safety module, trip and fault status indicators, reinforced anti-vibration layout.
Working Principle The module continuously measures the frequency of speed pulses. When the rotational speed exceeds the preset overspeed threshold, the hardware circuit immediately triggers the trip relay to cut off fuel or steam supply.
Installation Requirements Use independent speed sensor wiring, separate from governor speed signal cables, reliable safety grounding.
Usage Notes Calibrate overspeed threshold strictly according to unit manual, perform overspeed test periodically.
