Technical Specifications 24VDC power supply, multi-channel magnetic pickup pulse input. Operating temperature: -40℃ ~ +70℃, hardware latching trip relay output.
Functional Features Independent speed pulse sampling, overspeed threshold comparison, hardware trip action, trip status latch, channel fault self-test.
Application Scenarios Steam turbine and gas turbine overspeed safety protection, critical generator set overspeed trip systems.
Performance Parameters Ultra-fast trip response time, independent hardware logic, high safety integrity level.
Structural Characteristics Rack pluggable safety module, trip, alarm and channel fault indicator lights.
Working Principle The module samples speed pulses directly from magnetic pickup probes without relying on the main processor. When measured speed exceeds trip setpoint, the hardware circuit immediately activates the trip relay and locks the trip state.
Installation Requirements Speed sensor wiring is independent of governor speed signal cables, implement reliable safety grounding.
Usage Notes Complete overspeed functional test after installation, do not short or bypass trip contacts in normal operation.
