Industrial USB 2.0 Isolators - ULI-420 Series

Industrial USB 2.0 Isolators are 1 or 2 ports with 4kv isolation & ESD 15kV air, and 8kV contact protections against harmful noise and ground loops.

BB-UH401

Model BB-UH401 compact isolator protects valuable PCs and equipment from damaging EMI/RFI disturbances. Suitable for 12 Mbps full-speed USB devices. USB bus-power provides up to 100mA to attached downstream devices when attached to full-power (500 mA) USB host port. Note: data rate is factory set.
BB-UH401-2KV

Model UH401-2KV is a compact isolator that packs a powerful punch against electrical noise, surges and spikes with 2 kV isolation. Protect expensive PCs and equipment from damaging electrical storms, power surges and other high EMI/RFI disturbances. This isolation barrier eliminates ground loops which are disruptive in measurement applications. Suitable for 12 Mbps full-speed USB devices. The isolator is USB bus-powered and provides up to 100mA of current to attached downstream devices when attached to a full-power (500 mA) USB host port. USB cable included. Note: Data rate is preconfigured at the factory. High speed (480 Mbps) cannot be isolated with existing technology.
BB-UHR401

BB-UHR401 (ULI-421C) is a one-port ruggedized isolator designed and tested to meet heavy industrial EMC standards. It supports 4 kV isolation between the upstream and downstream USB ports to protect expensive equipment from dangerous ground loops and to help ensure data integrity.
BB-UHR402

The UHR402 is a twoport ruggedized isolator that it is designed and tested to meet heavy industrial EMC standards. High retention USB connectors hold standard USB cables tight and are perfect for high vibration applications – requiring up to 3.2 lbs force to disconnect them. The UHR402 has 4 kV isolation between the upstream and downstream USB ports to protect expensive equipment from dangerous ground loops and to help ensure data integrity. Heavy industrial EMC specifications allow the isolator to operate in unfriendly electrical environments – such as near variable frequency drives, motor control centers, welding, and other large electrical loads. The isolator is powered from an external 10 to 30 VDC power supply unit (required) and includes an international power supply that has USS, EU, and UK blades. Downstream port(s) provides up to 500 mA of power to connected USB devices. USB cable also included.
