  • Onboard 7-U USB extension port and compatible with USB 2.0/1.1 transmission.
  • Adopts industrial HUB chip and MTT technology, and allows stable and smooth concurrent 7-U USB connections.
  • ESD protection in each USB port, preventing electric surge damage and data loss.
  • Over-voltage protection, effectively preventing other high voltage power input from damaging the connected devices.
  • Multiple protection circuits: over-voltage, over-current, short circuit, over-temperature, reverse current, under voltage lock-out, 8KV ESD protection, filtering protection, etc.
  • LED indicators for monitoring operating statuses of power supply, network port, and USB ports.
  • Industrial grade metal case, rugged & durable, with mounting holes for easy installation.

Hardware Connection

  • Only supports 5V, and it will automatically power off when the voltage is too high.
  • 7 x USB output ports and its maximum output current is 1.2A. Exceeding this limit will trigger short-circuit protection, which requires the removal of the device to restore.
  • The operating temperature: -40 ℃~85 ℃. Note that there is no condensation, and this module is not waterproof.
  • LEDs indicate the enumerable situation of each USB. If there is one USB is connected and enumerated successfully, the corresponding LED will be on.
