Module Type Introduction

HWA143-TDM-PMC-V20 complies with IEEE1386.1 PMC bus standard, adopting TDM time division multiplexing parallel sampling architecture. It is specially designed for synchronous multi-physical quantity collection of turbine equipment, supporting IEPE vibration sensors, PT100 temperature transmitters, pressure and speed pulse signals. Independent isolated signal channels eliminate cross interference from strong electromagnetic field of turbine high-power equipment. Equipped with local real-time signal processing chip, it completes FFT spectrum analysis and fault feature extraction, uploads processed data to main controller via backplane bus, and supports hot-swap replacement without system shutdown. It is core spare part for online condition monitoring and predictive maintenance of power plant turbine units.
