Technical Specifications Supply voltage: 24 V DC; Speed input: variable reluctance pickup signal; Relay trip output; Operating temperature: -40 °C to +85 °C; Enclosure: IP30.
Functional Features Independent speed monitoring; hard relay trip output; self-test function; latching fault status.
Application Scenarios Gas turbine, steam turbine, gas engine overspeed safety protection, independent safety trip system.
Performance Parameters Speed detection accuracy: ±0.2% FS; Trip response time: <10 ms.
Material Composition Metal housing; safety-rated PCB; mechanical relay; signal conditioning circuit.
Structural Characteristics DIN rail mount module; speed input terminals and trip relay output terminals.
Working Principle The module measures speed signal from magnetic pickup continuously. When speed exceeds preset trip setpoint, internal relay activates and outputs hard contact trip signal to shut down fuel supply.
Installation Requirements DIN rail installation; connect speed pickup and trip relay circuit; configure overspeed threshold and perform functional test.
