Plug & Play Connectivity from The Modal Shop

Model 485B39: 2-channel, ICP (IEPE) sensor signal conditioner, BNC inputs, 24-bit USB digital signal output.

D485B39 front

A pocket-sized, dual-channel ICP® (IEPE) digital signal conditioner, Model 485B39 offers standard USB audio digital output. Plug & play signal conditioning makes for quick setup and intuitive functionality without the need for driver installation. The 485B39 powers ICP sensors through BNC connections while digitizing their signals over USB. Simply plug the unit into a USB port and view signals from accelerometers, microphones, hammers, or any other ICP-type sensor.

Existing third party windows, macOS, Android, iOS, or Linux software can be used to perform overall RMS measurements, FFTs, time waveforms, and octave measurements. The small form factor, versatility, and powerful software options make this the perfect tool for taking measurements on-the-go. Whether you're just learning about sensing, taking measurements on a daily basis, or simply want to add digital functionality to your existing sensors, the 485B39 will make a fine addition to your tool set.
