The UPort 204 from Moxa is an industrial-grade USB 2.0 hub with four ports, designed to expand a single USB port into four separate USB ports. It is intended for use in entry-level industrial applications where a reliable and robust interface for peripheral devices is required. The hub supports Hi-Speed data transfers up to 480 Mbps and is compatible with USB 1.1 and USB 2.0 standards, enabling broad use in existing systems. Connection is made via a USB Type-B connector, which is attached to a host system. The construction from polycarbonate (PC) ensures mechanical stability and protection against mechanical stress. Dimensions are 70 x 35 x 120 mm, and the device weighs 800 g. Operating temperature ranges from 0 to 60 °C, storage temperature from -20 to 75 °C, with humidity allowed between 5 and 95 % (non-condensing). The devices are designed for industrial environments where reliability and easy integration are required.

Applications

The UPort 204 is particularly suitable for mobile systems and industrial installations where multiple USB devices need to be connected to a host. Support for external power supply in the range of 12 to 40 VDC makes it flexible for use, even in vehicles or systems with industrial power supply. Integrated diagnostic LEDs allow for quick visual inspection of operational status. The high MTBF (Mean Time Between Failures) of 1,577,573 hours underscores the high reliability of the device.

Functions and Equipment in Detail

The hub provides up to 500 mA per port, sufficient to power many USB devices without additional power supply. Power supply is via a universal power adapter included in the delivery. Power consumption is 1.21 A at 12 VDC. The ESD protection class 4 (contact 8 kV / air 15 kV) protects the device against electrostatic discharges, which is important in industrial environments. Certifications according to EN 55032/24, CISPR 32, FCC Part 15B Class A, as well as environmental compliance with RoHS, CRoHS and WEEE, ensure adherence to applicable standards for electromagnetic compatibility and environmental protection.

Technology Explained Simply

Support for USB 2.0 enables data transfer rates up to 480 Mbps, sufficient for operating storage devices, printers, or other USB peripherals. USB-IF certification ensures compatibility with a wide range of operating systems and devices. External power supply via 12–40 VDC makes the hub independent of the host system’s power supply, which is particularly advantageous in mobile or industrial applications. Diagnostic LEDs indicate the status of individual ports, aiding in troubleshooting.

Compatibility and Accessories

The UPort 204 includes a USB cable Type A to Type B in the delivery, used to connect to the host system. The universal power adapter enables power supply within the specified voltage range. The quick installation guide and warranty and environmental declaration card are also included in the delivery. Compatibility with USB 1.1 and USB 2.0 ensures use with a wide range of devices.

Mounting and Installation

Installation is performed by connecting the USB cable Type A to Type B to the host computer or controller, then connecting the hub. Power supply is via the included universal power adapter, connected to a suitable power source. LED indicators assist in verifying connection and operational status. No special tools or additional installation steps are required.

Operational Advantages

The UPort 204 offers a reliable and robust expansion option for USB ports in industrial environments. The high MTBF, ESD protection class 4, and support for Hi-Speed data transfers ensure stable and high-performance use. External power supply enables flexible integration into various systems, and diagnostic LEDs simplify maintenance and fault diagnosis. Compliance with applicable standards for EMC and environmental protection ensures suitability for use in various industries.
