Overview

USB-303H2 is a USB 2.0 isolator and an isolated USB hub featuring two independently isolated ports.
It provicles isolation of USB interface, enabling separation between USB host equipment (such as computers) and peripheral devises.
There are two separate isolation circuits, providing isolation between all USB ports (host, portA and portB).
It supports USB 2.0 High Speed (480Mbps), Full Speed (12Mbps) and Low Speed (1.5Mbps).
By isolating the USB interface, it offers benefits such as improved noise resistance and enhanced precision of external analog devices (by isolating GND).

Features

The two downstream ports are independently isolated.
Two separate isolation circuits provide isolation among all USB ports (host, Port A, and Port B).
Supports USB 2.0 High Speed (480 Mbps), Full Speed (12 Mbps), and Low Speed (1.5 Mbps) with automatic speed switching.
High-retention USB Type-B connector on the host side.
SG/FG switch and FG terminal on the host side.
Plug-and-play operation; no driver installation required; OS-independent.
Supports both bus-powered and self-powered operation.
Equipped with an isolated DC/DC converter with sufficient capacity.
The target-side power supply is synchronized with the host side.
Isolation withstand voltage: DC 1500 V.
ESD protection for USB lines.
Housing material: Plastic (safe Isolation)
DIN rail, magnet, and screw mountable (Attachment is required)
Includes a 1.8 m USB cable.
Includes an AC adapter (DC 6 V).
Free from the 10 RoHS-restricted substances.
MADE IN JAPAN
