Black Box Industrial-Grade Usb Hub, 7-Port - Usb - External 16Ff79

273 USD

A great choice for factory, utility, and engineering applications, the Black Box® Industrial-Grade USB Hub, 7-Port enables more reliable USB device connectivity in harsh environments

Through its terminal block input or locking barrel plug, it receives power externally from a 10−30-VDC source

The hub includes hardware for mounting, including a DIN rail mounting bracket and panel-mount brackets.

The hub expands one USB port into seven, so you can connect additional USB peripherals to your host system via its upstream port

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

(Disconnecting them requires up to 3.2 pounds of force.) Cables click into the ports securely to help eliminate data loss

Also, because it can be powered via the USB bus, you don’t need to locate it next to a power outlet

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

But, if your downstream USB devices require extra power, the hub can be used with an external power supply

When the hub is using USB bus power, it provides a maximum of 100 mA to each downstream port; when powered externally, it provides 500 mA to each downstream port

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
