Technical Specifications 24VDC operating power; speed pulse input; relay trip output; built-in speed monitoring circuit. Operating temperature: -40℃ ~ +85℃.
Functional Features Independent speed monitoring; overspeed detection and trip output; fault self-check; alarm signal output.
Application Scenarios Diesel engine, gas engine and turbine safety overspeed protection systems.
Performance Parameters Fast trip response, high speed detection accuracy, independent protection channel separate from governor.
Structural Characteristics Metal shielding housing, DIN rail mounting, pluggable terminal blocks.
Working Principle The module continuously receives speed pulse signals from magnetic pickup sensor, calculates real-time rotating speed. When speed exceeds the preset threshold, the internal circuit actuates trip relay to cut off fuel or gas supply.
Installation Requirements Install in control cabinet; use shielded twisted pair for speed sensor wiring.
Usage Notes Test overspeed trip function during unit commissioning; verify sensor wiring and trip loop periodically.
