　　内容介绍
　　USB-4750 is a 32-channel isolated digital I/O module for the USB bus. With isolation protection of 2,500 VDC, 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 on digital input interrupt lines to a PC.
