USB-4750 32-ch Isolated Digital I/O USB Module Features Compatible with USB 1.1/2.0 Bus-powered 16 isolated DI and 16 isolated DO channels High voltage isolation on all channels (2,500 VDC) High sink current on isolated output channels (100 mA/Channels) Supports 5 ~ 50 VDC isolated input channels Interrupt handling Timer/counter capability Suitable for DIN-rail mounting One lockable USB cable for secure connection included RoHS COMPLIANT 2002/95/EC 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 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 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.
