Industrial USB Hub Features and Benefits

When developing or advancing the automation of factory processing we tend to think of IoT (Internet of Things) machines and applications. This rapid change in the connectivity of devices and machines to capture and share data has been revolutionary to many industries. Quality and speed of services has improved, together with closer monitoring and lower costs.

This change of working has also meant there has been a rapid growth in networking within industrial environments. Industrial environments can be harsh places for electronic devices and where mission critical applications are in situ, we use certified embedded computers, screens and peripherals to protect the environment, workers and the industrial process. This should include the correct industrial grade USB Hubs when creating a local network.

ACCESI/O offer a range of high-performance, rugged industrial grade USB Hubs here, which offer features important to industrial applications such as wide operating temperature, latched USB connectors, isolation and protection against transient voltage surges. Available housed in a rugged enclosure or as an OEM bare board, full software support is provided with each device.

ACCESI/O Tru-Iso™ products are designed under IPC-2221B Generic Standard on Printed Board Design. The circuit is isolated with a ≥ 300mil gap between all signal and plane layers between the upstream port and the downstream ports. This gap is rated under IPC-2221B at a peak working voltage of 1500V (Upstream to Downstream). The circuit uses a chip-level high-frequency DC-DC isolator which is rated at 5000VRMS for 1 minute under UL 1577 optical isolators standard. This isolation component has an over 50 year isolation lifespan even if the isolation voltage potential is in excess of 846 volts AC. Tru-Iso™ products are also designed to meet the EN60601 medical electrical equipment standard. 

  • ESD Protection: ±20kV on all signal pins (IEC 61000-4-2 Level 4)
  • Tru-Iso™: IPC-2221B, UL60590-1, UL1577 (4000V isolation meets EN60601)
  • Up- to Downstream: 1500V peak (AC or DC)
  • Max Transient Isolation: 4000V rms
  • Max Work Isolation: 863V peak

OEM Bare Boards

The OEM (board only) versions are available for all the above hubs. What makes the OEM options unique is that the PCB size and pre-drilled mounting holes match the PC/104 form factor (without the bus connections). This ensures easy installation using standard standoffs inside most enclosures or systems. The board can be added to any PC/104-based stack by connecting it to a USB port usually included on-board with embedded CPU form factors.
