  • Connect four USB devices through one port saving cabinet space
  • USB 3.0 SuperSpeed delivers maximum data throughput for industrial use

  • Dual redundant power inputs maintain operation if one supply fails
  • Built-in overvoltage protection shields connected devices from surges

Industrial USB 3.0 Hub

The IH-304 is a USB 3.0 device server built for industrial environments. It lets operators connect up to four USB peripherals through a single host port. The unit mounts on a standard 35 mm DIN rail for quick integration into control cabinets or server racks. No special drivers are required for basic operation.

Four-Port Capacity and Power Redundancy

Four SuperSpeed ports handle data transfers and can also charge attached devices. Dual power inputs provide redundancy so the hub stays online if one supply fails. Integrated overvoltage protection shields connected hardware from transients caused by faulty supplies or switching events. The hub adds no software overhead to the host system.

Replaces Ad-Hoc USB Extensions

This hub replaces improvised cable runs and consumer-grade hubs that lack rail mounting or surge protection. The upgrade is worth it when a cabinet or rack needs a compact, rugged way to consolidate multiple USB instruments on one host connection. It is not suited for setups that require more than four downstream ports or non-USB interfaces.

Questions about this item

Will the IH-304 USB 3.0 hub work with my existing USB 2.0 industrial sensors and controllers?

Yes, the hub supports USB 3.0 SuperSpeed and remains backward compatible with USB 2.0 and 1.1 devices, so your existing sensors and controllers will operate normally on any of the four ports.

How can I confirm the IH-304 is powered and passing data after mounting it on the 35 mm DIN rail?

The unit powers from dual redundant supplies; once both inputs are live the hub enumerates on the upstream USB 3.0 link and all four downstream ports become active, which you can verify in the host OS device manager.

Does the M07250 package include the DIN-rail clips and power cables, or must I order them separately?

The hub ships in a top-hat rail housing ready for 35 mm DIN EN 60715 mounting; power terminals are built in for dual-supply wiring, so no separate rail clips or proprietary cables are required.
