Black Box Industrial-Grade USB Hub - switch - 4 ports - TAA Compliant

Now you can connect four USB 2.0 devices in industrial settings without worrying about accidental disconnects or ESD damage to your connected USB devices. This Industrial USB 2.0 Hub features high-retention ports that ensure a tight connection-even in high-vibration environments. Housed in a durable IP30-rated metal enclosure. UL(r) listed for use in Class 1 Division 2 hazardous areas. Tested for 50G shock and 4g vibration. USB 1.1 and USB 2.0 compatible. Supports USB speeds of 12 Mbps. Includes panel- and DIN rail mounting hardware. Use either a locking barrel plug and terminal block for power input. A great choice for factory utility engineering and even healthcare applications the Black Box(r) Industrial-Grade USB Hub 4-Port with Isolation enables more reliable USB device connectivity in harsh environments. The hub expands one USB port into four so you can connect additional USB peripherals to your host system via its upstream port. Considerably more rugged than ordinary office-grade USB hubs it's designed to allow you to operate USB peripherals in areas with lots of electromagnetic interference (EMI) and prevent data errors caused by such interference. Tested to meet heavy industrial EMC standards the hub is also designed to prevent ESD (electrostatic discharge) from damaging your connected USB devices- which makes it ideal for use near electronically noisy motor controls variable frequency drives and equipment with large electrical loads. The hub supports full-speed (12 Mbps) USB 2.0 connections and offers isolation from ground loops. Use it for instance in areas where you are connecting a PLC in one cabinet to a drive-in another cabinet or in a tightly packed medical cart. It enables data to pass unaffected while 4-kV isolation between the upstream and downstream USB ports helps prevent harm to important USB devices. Because the hub has high-retention ports for device connections standard USB cables are a lot less likely to shake loose- even in environments with lots of equipment vibration. (Disconnecting them requires up to 3.2 pounds of force.) Cables click into the ports securely to help eliminate data loss. Through its terminal block input or locking barrel plug it receives power externally from a 10- 30-VDC source and provides 500 mA to each downstream port. The hub includes hardware for mounting including a DIN rail mounting bracket and panel-mount brackets.
