Rectangular metal industrial USB hub with multiple ports

POLY

POLY USBHub3+ Programmable Industrial 9-port Managed USB Hub 2583-87540-001

SKU CH-BJTP-YZ5FM

A programmable 9-port industrial USB hub with per-port power control, voltage and current monitoring, and two upstream ports for host switching

  • Changer TypeUSB A to B
  • Programmable per-port power control for industrial reliability
  • 9 downstream and 2 upstream ports with individual voltage and current monitoring
  • Software management via cross-platform app or Python and C++ API
  • DIN rail mountable design withstands ±15 kV ESD strikes
  • Auto-switch between two host computers expands to multiple hubs

Managed 9-port USB hub

The POLY USBHub3+ is a programmable industrial-grade hub with nine downstream and two upstream USB ports. Each port can be individually controlled and measured for voltage, current and data transfer. Software management is available via a cross-platform application or through Python and C++ APIs for automated workflows. The unit is DIN-rail mountable and built to withstand ±15 kV ESD strikes.

Suited for test labs and fixed installations

Developers and engineers who need per-port power switching, current limiting and automated port sequencing in manufacturing, conference-room or laboratory environments will benefit from the managed features. Buyers who only need a basic always-on hub for simple peripheral expansion without software control or industrial ESD protection should look elsewhere.

Two upstream ports with auto-switching

The hub provides two upstream connections that can automatically switch between host computers, enabling shared access to the nine downstream devices. This dual-host capability is the key specification that determines whether the hub fits a given test or deployment setup.

Questions about this item

How do I decide between the two upstream ports and the expansion port for my setup?

The hub provides two upstream ports for connecting to separate host computers and an expansion port for linking additional hubs, letting you switch or daisy-chain as needed.

What does the per-port 4 A fast-charge rating mean when I plug in a phone or tablet?

Each downstream port can deliver up to 4 A, so phones and tablets charge at their maximum supported rate while the hub monitors voltage and current in real time.

How does the USB 5 Gbps interface limit actual transfer speeds with multiple drives attached?

The 5 Gbps SuperSpeed link is shared across all active downstream ports, so simultaneous large-file copies will divide the available bandwidth among them.
