    Description

    USB Opto-Isolator


    Quick Facts

    • Protects a PC or Mac plus up to four USB 1.1 devices.
    • Designed specifically for use in environments heavily susceptible to ground loops.

     

    Further Details

    • Supports both 1.5- and 12-Mbps USB devices.
    • Features overcurrent protection, electrostatic discharge (ESD) protection, and power switching on all ports.
    • Provides 2500 volts of isolation between the upstream port and downstream ports.

      The Universal Serial Bus (USB) interface become the standard desktop connection interface. But extending the USB bus beyond the desktop can expose your system to ground loops, spikes, and surges, too.

      Our USB Opto-Isolator provides the protection against such power anomalies that can damage your PC and the peripherals attached via an extended USB bus. Ideal for industrial and commercial applications, this 4-port device features 2500-volt isolation between the upstream (host computer) port and the four downstream (peripheral) ports. It even features individual power management for each port. If there’s a short circuit on a port, the USB Opto-Isolator detects it and shuts down that port automatically while allowing the other ports to continue operating.

      Plus, it’s easy to set up. Just plug in your host computer or hub to the Type A upstream connector (on a handy 1-meter [3.2-ft.] cable lead), and plug in your downstream USB devices. You never have to deal with IRQ jumpers or device addresses. Your PC or Mac recognizes the device and runs diagnostics automatically, so you’re up and running within minutes!
