With 5 USB 2.0 ports, USB-4620 enhances its isolation protection to 3,000 VDC for each downstream port, making every USB device connected with USB-4620 could operate independently and safely. Designed for industrial applications, USB-4620 is able to be mounted through several types, such as DIN-rail mounting, wall mount, and VESA mount. Other than that, USB-4620 is equipped with lockable USB connectors and screw holes, allowing each device to be connected firmly with USB-4620. Though the standard USB cable is made for easy plugging and removing, it is critical to have reliable connections while operating for automation control and online production applications.
