Technical Specifications 24VDC power supply, compatible with magnetic pickup pulse signals. Operating temperature: -40℃ ~ +70℃, synchronous multi-channel pulse signal processing.
Functional Features Redundant speed signal shaping, channel fault detection, automatic signal switching, speed signal backup output, fault alarm.
Application Scenarios High-reliability gas turbine and steam turbine overspeed protection systems, important generator sets requiring redundant speed measurement.
Performance Parameters Synchronous sampling of multi-channel signals, fast channel switching, consistent signal output characteristics.
Structural Characteristics Rack pluggable PCB module, multi-channel status indicator lights, redundant circuit layout.
Working Principle The module synchronously receives the speed pulse signals from multiple speed sensors, processes each signal independently, monitors the health status of each channel, and provides backup standard speed signals for the control system.
Installation Requirements Install together with the main speed processing module, each sensor uses independent shielded signal cables.
Usage Notes Calibrate the signal consistency of all channels after installation, regularly test the redundant switching function.
