It provides up to eight direct seismic input channels, supports high-resolution signal conversion, and interfaces with two-wire constant-current sensors. The card combines seismic data capture, sensor excitation, and signal processing functions within a single monitoring architecture.\u003c\/p\u003e\n\u003ch3\u003eSignal Acquisition and Processing\u003c\/h3\u003e\n\u003cp\u003eThe card supports up to 8 independent seismic input channels, allowing multiple vibration or seismic measurement points to be monitored from a single module. A 16-bit A\/D converter provides high-resolution signal digitization for detailed waveform acquisition and analysis.\u003c\/p\u003e\n\u003cp\u003eWith a frequency bandwidth extending to 4 kHz, the module can capture higher-frequency vibration content associated with machinery condition monitoring applications. Both synchronous and asynchronous processing modes are supported, enabling data collection strategies suited to different diagnostic requirements.\u003c\/p\u003e\n\u003ch3\u003eSensor Interface\u003c\/h3\u003e\n\u003cp\u003eThe 164746-01 is optimized for two-wire constant-current sensors, including compatible Bently Nevada AM Series accelerometers. Integrated sensor excitation simplifies field wiring by providing the operating power required by connected transducers.\u003c\/p\u003e\n\u003cp\u003eThe module supplies a constant bias current of 3.3 mA and provides a sensor excitation voltage of +24 VDC (± 5%).
