Technical Specifications Adapted to magnetic pickup AC pulse signals, 24VDC auxiliary power supply. Operating temperature: -40℃ ~ +70℃, built-in low-pass filter circuit.
Functional Features Speed signal terminal conversion, pulse noise filtering, open circuit detection for speed probes, signal shunt for redundant speed channels.
Application Scenarios Generator speed measurement loops, gas turbine overspeed protection systems, diesel engine governor feedback circuits.
Performance Parameters Low attenuation for weak pulse signals, wide frequency response range, strong anti-interference performance.
Structural Characteristics Terminal PCB board with dedicated pulse signal terminals, speed signal status LED indicators.
Working Principle The raw AC pulse signal from the magnetic pickup sensor is connected to the terminals of this board. After filtering clutter interference, the signal is distributed to one or multiple speed processing modules for speed sampling and calculation.
Installation Requirements Install as close to the speed sensor as possible, use shielded twisted pair cables for speed signal wiring.
Usage Notes Avoid parallel laying with inverter power cables, check the air gap and wiring integrity of speed probes during maintenance.
