StarTech.com 1 USB 2.0 Galvanic Isolation USB Extender

StarTech USB Extender, USB 2.0 Specification, Galvanic Isolation Transmission Method - U1-USB-ISOLATOR

This USB extender provides galvanic isolation for a single USB connection to prevent direct electrical continuity between host and device. Designed for USB 2.0 data rates, it enables isolated USB data transmission in environments where separation between circuits is required. The unit is intended for integration into automation, electronics and electrical workflows where signal integrity and isolation are necessary.

Features and Benefits:

• Galvanic isolation protects equipment and personnel
  Supports USB 2.0 throughput for standard peripherals
  Single-port design simplifies integration into test setups
  Low-power consumption rated at 500 mW reduces system load
  Complies with CE LVD requirements for regulated installations
  Meets IEC/EN 62368-1 for recognised safety criteria

Applications

• Suitable for isolating sensors and control interfaces in automation racks
  Ideal for connecting measurement instruments in electronics labs
  Used with diagnostic tools in electrical maintenance areas
  Can be used for protected data links in mechanical test benches

How does the device affect signal compatibility with USB peripherals?

It maintains USB 2.0 signalling so standard high-speed and full-speed peripherals operate without protocol conversion while providing galvanic separation.

What power constraints should be considered when integrating it into a system?

The unit draws up to 500 mW, so power budgeting should account for this additional low-power load when designing supply arrangements.

What approvals relate to safety and regulatory installation requirements?

The unit adheres to CE LVD directives and the IEC/EN 62368-1 standard, indicating conformity with recognised electrical safety norms.

How many downstream devices can be connected through it?

It provides a single USB port for one downstream device, suited to single-channel isolated connections.
