Introduction
USB-4702/4704 are low-cost USB data acquisition modules. You no longer need to open the chassis to install DAQ modules. Just plug in the module, then get the data. It’s easy
to use and efficient. Reliable and rugged enough for industrial applications, yet affordable for home projects, USB-4702/4704 are the perfect way to add measurement and control
capability to any USB capable computer. It obtains all required power from the USB port, so no external power connection is ever required. With the features of USB-4702/4704, they
are your most cost effective choice of lab or production line test & measurement tool.

ƒƒ Max. Sampling Rate USB-4702: 10 kS/s max.
USB-4704: 48 kS/s max.
Note: The sampling rate for each channels will be affected by used channel number.
For example, if 4 channels of USB-4702 are used, the sampling rate is 10k/4 = 2.5 kS/s per
channel.
