Programmable industrial USB hub, 4 downstream, 2 upstream Control and measure port voltage and current and data Programming APIs in C++ and Python DIN rail mountable 12V, 5A Power supply and USB cable included The USBHub2x4 is a software controlled USB 2.0 (high-speed 480Mbps) hub featuring 4 device downstream ports with standard USB type-A receptacles and each port is capable of delivering up to 2.5A simultaneously. Each downstream port can be individually turned on or off, and power and data can be separately enabled or disabled. With two host (upstream) connections using USB Mini-B connectors, the USBHub2x4 is perfect for environments where multiple devices need to be shared or switched between two host computers. E.g.: software regression testing, smartphone software development and validation, Android software development and validation, USB device regression testing, manufacturing testing, device burn-in testing and USB device charge-curve testing. Upstream and downstream USB signal levels can be boosted to account for difficult interconnection environments. Designed for harsh industrial environments, the USBHub2x4 is built inside a rugged powder-coated metal housing with DIN rail mount points. The system is designed to withstand the harshest ESD strikes up to ±30kV air-discharge (twice the IEC 61000-4-2 level 4 spec) and is fully operational up to 50C ambient temperatures. It can even survive sitting on a developer's desk! The powerful BrainStem programming APIs in C++ and Python allows for high-level applications to control the advanced features of the hub. The Acroname Programmable USBHub2x4 ships with 120-240VAC, 50/60Hz, 12V, 5A AC to DC power supply and USB cable.
