GE VMVIVME-3125 – VMEbus 32-Channel High-Speed Analog Input Module

In stock

Product Introduction:
The GE VMVIVME-3125 is a high-speed, 32-channel analog input module for VMEbus systems. The “VMVIVME” prefix is an alternate spelling of “VMIVME” used in some GE documentation and part number databases, but the functionality is identical to the VMIVME-3125. This board provides 32 channels of simultaneous analog-to-digital conversion at 125 kilosamples per second per channel. It is designed for high-speed data acquisition applications where capturing fast transients and high-frequency signals is critical, such as vibration monitoring, seismic data collection, and power quality analysis. The 125 kSPS sampling rate is 100 times faster than standard process control analog inputs, making this board essential for any application requiring detailed waveform capture.
