The USB-4750, 4751, and 4751L are multi-function USB I/O modules starting at $155. (Cincinnati, Ohio – 3/22/2007) - The eAutomation Group of Advantech introduces 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). These modules have been specifically designed for industrial environments and include USB connectors with screw fasteners and DIN-rail mounting kits. They draw power directly from the USB port and therefore do not require an external power supply.
Relying on the plug-and-play features of USB, these modules are so easy to use that users need less than five minutes to setup before acquiring data.The USB-4750 has isolation protection of 2,500 Vdc, making it an ideal solution for industrial applications where high voltage protection is required. It has 16 isolated digital inputs and 16 isolated digital output channels, supports 5 ~ 40 Vdc isolated input channels, and has a high sink current on the isolated output channels (100mA/channel). The USB-4751 has six 8-bit I/O ports whereas the USB-4751L has three 8-bit ports. They emulate mode 0 of 8255 PPI and their buffered circuits provide 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. Also, there’s one event counter and three 16-bit timers, which can be cascaded to become a 32-bit timer.All the modules include interrupt handling and are compatible with USB 1.1/2.0These modules are available for purchase directly from Advantech or from any Advantech distribution partner.
