The USB-4750, 32-channel isolated digital I/O USB module, the USB-4751, 48-channel TTL digital I/O USB module, and the USB-4751L, 24-channel TTL digital I/O USB module, draw power directly from the USB port. Setup is plug-and-play.
The USB-4750 has isolation protection of 2,500 Vdc, with 16 isolated digital inputs and 16 isolated digital output channels. It supports 5 to 40 Vdc isolated input channels and has a high sink current on the isolated output channels, with 100mA per channel.
The USB-4751 and the USB 4751L have six 8-bit I/O ports three 8-bit ports, respectively. They emulate mode 0 of 8255 PPI, and their buffered circuits give higher driving capacity than the 8255. A 50-pin IDC box header connector (Opto-22 compatible) provides an easy interface to Relay or SSR daughter boards. What’s more one event counter and three 16-bit timers can be cascaded for a 32-bit timer.
All the modules include interrupt handling and are compatible with USB 1.1/2.0
