Introduction
The USB-4700 series consists of true plug & play data acquisition devices. No more opening up your computer chassis to install boards-just plug in the module, then get the data.
It’s easy and efficient. USB-4750 is a 32-channel isolated digital I/O module. With isolation protection of 2,500 V
DC
, and dry contact support, USB-4750 is ideal for industrial applications
where high-voltage protection is required. Each I/O channel of the USB-4750 corresponds to a bit in an I/O port. This makes USB-4750 very easy to program. This module also offers
a counter or timer and one digital input interrupt lines to a PC. So users can then easily do configurations by software.
Reliable and rugged enough for industrial applications, yet inexpensive enough for home projects, the USB-4750 is the perfect way to add measurement and control capability to any
USB capable computer. The USB-4750 is fully USB plug & play and easy to use. It obtains all required power from the USB port, so no external power connection is ever required.
