Technical Specifications 24VDC power supply; frequency signal input channels; built-in event recording function; operating temperature -40℃ ~ +85℃.
Functional Features Speed signal acquisition and calculation, overspeed trip protection, fault diagnosis, alarm output and event log storage.
Application Scenarios Gas engine, diesel generator and small turbine overspeed protection cabinets.
Performance Parameters Fast trip response, reliable speed identification, stable continuous operation under vibration environment.
Structural Characteristics Rack-mounted metal shielding housing, pluggable terminal blocks for speed signal wiring.
Working Principle Receive pulse signals from magnetic pickup sensors, calculate real-time rotational speed, compare value with preset protection threshold and trigger shutdown protection once exceeded.
Installation Requirements Install inside sealed control cabinet; use shielded cable for speed signal wiring and ensure reliable grounding.
Usage Notes Perform overspeed function test before unit commissioning; back up fault logs periodically.
